Wouldn't it be cheaper just to undercoat the painted part of the bumper? I know it would not look that great but when you are ready to sell the truck, just remove the undercoat with mineral spirits. And the bumper will look like new. A $ 8 fix.

No, you cant just spray undercoat over clearcoat it wont stick for long. Mineral spirits damage clearcoat as well, and it wouldn't look good on a clean and classy truck like these.

Mineral spirits wont harm the paint at all, might strip the wax but the paint will be fine. People have been using mineral spirits to remove road tar for years.

 

Clear bra is the best answer other than a strip and repaint and even then you would still want the clear bra.

I just got a quote from the gm body shop at the dealer where I do my business and it will cost 800.00 to repaint. They value my business more than GM does. They are going to help me out.

Mineral spirits are derived from turpentine, they are mostly used to clean paint brushes of paint, what do you think that does to clearcoat??

 

And no a clear 3m bra is not the best answer as it tends to lift over time allowing in water moisture dirt causing rust, this has been an issue with the 3m strips that come on the silverado /sierra boxes at the bottom of the box.

Nothing. Absolutely nothing. WD-40 contains about 60% of mineral spirits by volume. Are you telling me that WD 40 eats through clearcoat when you use it to remove tar from your vehicle?

Its not 60% its 50%, and thats why WD40 is the worst lubricant and has to be reapplied more then any other lubricant Ive ever used. Nowehere did I say it eats through anything, no need to be making things up. Im saying It has an effect on clearcoat. Just like leaving a rusted bolt in a can of Pepsi, after alittle while it comes out less rusted. You can keep using MS on your clearcoat, you will love how it looks in 5 years.

I do not use mineral spirits on my clearcoat. I occassionally use it to remove small tar spots, after which I wet the cleaned area with water and wax afterwards.. Most commercial tar removers contain mineral spirits.

Good that you clean it and wax it, that's the way to do it. Not to leave it on.

I have the same issue on the seams that my clear bra does not cover, the bumper seems to chip significantly easier than the metal portion of the parts, my hood also chipped at the corner, which is aluminum. I guess anything other than the main body chips easier than they are suppose to be. I am glad that I have the clear bra so it is not as bad.....

I had the same issue with paint chips in the bumper. Had a dealer supposedly fix which they just used touch up paint. Touch up paint did not match and had it out with the dealer. Contacted GM customer service with multiple emails and PM's on here to GM Customer Service. Finally had the front bumper painted under warranty. Now I just have to wait 30 days to have the Xpel paint protection done. Meanwhile I am not driving on the highway or driving much until then. I know most guys can't do that but I ain't taking chances.

I admit I no nothing about this subject (we don't get much sand on the roads in SC but we do get lots of rocks thrown up from cars and trucks in front), but, it's known that carnauba wax only lasts 6 - 8 weeks and then needs to be reapplied. I just discovered using a sealer instead of wax - suppose to last 8 - 12 months (and so easy to apply - much easier than wax, and sooo slick - noting sticks to it). I've also seen a few trucks that had Line-X applied (colors available) to lower front and sides of new trucks - looks okay but probably not as nice as the painted bumper - but it will protect! Just saying ...

I will never have a painted bumper again, my last 3 denalis, the bumpers were all rusting within 3 years, I wanted a 2014, but still painted, so I went cheaper, with the Silverado chrome bumper

Here is how U Haul solved this problem on their older F350 van trucks. The trucks came with painted steel front bumpers. U Haul obviously got tired of repairing paint chips and rust on the front bumpers, so they came up with a light unpainted gray plastic bumper cover which they riveted to the heavy steel bumper with several rivets. Problem solved and it does not even look that bad. Unpainted plastic does not chip or otherwise deteriorate from gravel and rocks and bumper underneath look good as new.

Have the exact same truck and I live in Georgia where the roads are fantastic without the sand and rocks and mine is chipped just as bad! I'm not sure what they did this time but it's been the worst truck ever for chipping! I need to see how many complaints there are on this and maybe push my dealership to fix it. I am still under warranty on it and it seems to be a defect.

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?

      There's a bunch of tea leaves that you've read, but in any case the delayed timing is unusual. Not sure how that relates to the rich at idle vs. 'normal' while driving.   If you're in this deep, might be worth investigating, and re-learning the sensor. What have you got to lose? Plus, it properly fixes the timing cover leak.

      The only problem I have seen this cause is longer crank times.

      Injector is being sent off today for rebuild and I estimate I'll have it back in 10 days or so.   It may not be the injector...of course...now that I've torn down the intake again. But, let's rule out the injector and replace those spider legs that have been almost rubbed through.   The truck has always had negative timing and I'm reading "normal" timing at warm idle should be +16 or so. I'm negative 16 to 25 or more, and it's always been like that since I bought it.   A light turned on upstairs last night in the old noggin. Rare, I know...   This will be wild, if it turns out to be the cause!   In 2001, according to the old service documentation, the muffler was replaced. Why? I have no idea, it wouldn't have been rusted through by then. But they did a crappy job.   In 2019, another shop replaced it and noted the prior install was poorly done on the work order. "Exhaust system vibrates on crossmember". Except...I guess they just left it be? I believe the husband, the couple who were original owners, had passed by then. Maybe she said it's just not worth it to have the exhaust system fixed and declined repairs. Very few miles were driven between 2019 and 2025.   The exhaust system vibrates heavily on the crossmember and you can feel it and REALLY hear it, even today. Not always, but at idle, it gets going pretty good sometimes.   What if....   ....What if that's enough to trigger one or both of the knock sensors? Could it be tricking the sensors into sensing knock, so it's pulling timing aggressively? Pulling timing heavily means it's firing after the piston reaches full height which means incomplete burn which means the O2 sensor is sensing a rich condition, which means I've been chasing my tail, and what I thought was an inconsequential problem (janky exhaust) has been THE issue for this truck for 25 solid years?   That would be wild. Maybe it IS wild.   The service documentation thereafter, for years, shows visits for rough idle, replacing O2's, replacing the cat, replacing plugs and wires, a misfire condition, like they could never solve the issue. The injector has been replaced 4 times in 80k miles, that's just crazy.   The secondary theory....   The engine has clearly had a leak at the front seal for a very long time (the greasy trench...). I think the truck changed hands quickly ~2025 because there's Napa receipts from someone I don't recognize in the ownership history. They apparently replaced the timing cover seal, and they did a terrible job. There's RTV smeared all over and the leak I had reduced to a weep by snugging the front oil pan bolts is now a leak again.   HOWEVER....I read about replacing the crankshaft position sensor. Any time the ckp sensor is disturbed or timing cover is removed, the truck requires relearning, and that can only be done through a bi-directional scan tool. Skippy with the RTV probably didn't do the relearn procedure is my guess. His scan tool is lost in a pile of RTV goo somewhere.   So, it's very possible the sensor has been disturbed and the truck is just running on the old learn data but not setting a code for anything. The distributor has since been replaced and so has the camshaft position sensor, so all bets are off for that thing.   In the theme of one step forward, two steps back, I returned the accumulator for the AC. The gal I've been working with at O'Really's has been great. She refunded it under manufacturer's defect and we compared it to the replacement I ordered, and sure enough, the replacement is machined very differently (and a gauge actually fits on it!).   Got it home, installed it, started vacuuming it down.... and I couldn't get good vacuum.   The high side service port, where I replaced the old GM ball valve suspecting that was a source of the previous leak....well, I've clearly exposed whatever pre-existing crack in the line where the service port is welded, and made it much worse. Blessing in disguise? Except there goes another $25, now I'm waiting for a replacement AC line.   In 10-ish days ALL the parts will be here. Rebuilt injector, new exhaust system, new cat, new high pressure AC line.   Oh, did I mention the squeaking ISN'T coming from the AC pump? The truck still squeaks when started, and there were words after I started it with the new AC pump installed. But, there was more to replacing the AC pump for just a squeak. A truck with good working AC is something of value, for the comfort alone.   I've ordered a new harmonic balancer because, 30 years is a good run for one of those. Rule it out. The squeak may be something more sinister, though. I'm worried about that ckp sensor and if it was shimmed correctly, or if the timing set was installed correctly. The squeak may be coming from UNDER the timing cover.   At this point, once I get it put back together, I'm thinking I'll take a 50 mile victory lap and then promptly put it up for sale. This truck is cursed. Betty, from beyond the grave, doesn't want anyone messing with her Blazer. Or maybe she's getting revenge for 30 years of shop visits with that thing.
