Rust Problem...

[ocean4200]

You cannot stop rust actually... It is a matter of time before the rust get into the door. The problem is that the bottom of the door is no "U" shaped to let the water get out... When you drive the truck in rain, the water goes directly to the bottom of the door. Now, here is what you need to do:

 

1- scratch the paint where the rust is.

2- Use a Zinc primer can and apply 3 light coats on the rust. Zinc primer is like dark green...

3- Apply your color paint in spray can (3 light coats)

4- let it dry (doors opens) for one day (be careful of theives). Try to do it in a garage.

5- After one week, do a oil/grease rust treatment. Apply the oil inside and outside the bottom of the door. Use oil for rust treatment only! not conventional oil!

6- Install Mud flap/pad in front to prevent water to go near the bottom of the doors

7- install 6 inches steps bar to add a good water protection

8- You can also install a 1 inch wide rubber band (length of your door) on top of the paint so the water doesn't go futher... It will act like a water barrier. Car stores sell it for any application...

 

that should do the trick for a while... Depending of your habbits

 

Zinc primer will last 2 years minimum. Also, you must always clean the bottom of the doors each year. Remember, when you see rust, you MUST solve it right-O-Way~!

How long do you give these doors to last? Maybe it would be easier just putting on a new door when the time comes?

 

You definitely would be in a good position to put a new door on when it gets to that point, just depends on what you get from body shops as far as pricing is concerned.

 

The doors you have, in the shape they're in now, will probably give you a few more years of good service, but I'd expect to see the paint to start bubbling up sooner than that on the outside of the door. You can continue to "hide" that, but it's really up to you how much you worry about it.

Is that Eastwood stuff any good I used? It's supposed to be similair I guess.

I have yet to see an Eastwood product that doesn't do what it says, but I haven't used that particular product before. Personally I use Permatex "Naval Jelly" which is a thicker paste-consistency product that converts rust. It just brushes on and turns rust areas into a layer of black primer.

 

Most of the rust repairs I do are similar in nature to what you did, just a short-term cover up for someone that is going to sell/trade a vehicle in. Grind the bubbles off, use naval jelly, cover with a skim-coat of body filler (spot putty usually), block, prime, and paint. It's a method that won't last, but if you're just trying to hide it "quick 'n dirty" to increase resale for as cheap as possible, it works great.

my 03 burban has no visible rust on the doors or inside the doors. there is normal rust underneath the truck but its not that bad.. and have not looked at my silverado yet but i guess i will now

[brandon_guzzo]

Haven't seen a GM SUV/Truck without that yet. My '03 TrailBlazer had it, my '05 Suburban has it. The '05 Suburban has been rust treated as well. Nowhere near as bad as those pictures, but it does have it.

 

 

My 2000 silverado deos not have that rust mind you i have it rust proofed every year. My truck does have the normal rust on the frame but nothing on the body that ive seen

[02silveradols]

My body is also solid...I will be doing the frame soon and will get pictures of that up.

I used this product soon after I bought my truck. I sprayed the folded creases on the inside bottom of all doors, and hood edges. It is a wax like substance that penetrates into spaces between crimped panels and stays tacky and keeps out moisture. Costs about $ 6/can, more than enough to do the whole truck.

I know I'm digging up a 2+ year old thread but do you have any updates on how your door is holding up? I'm in Kalamazoo, Michigan and my 2003 GMC has a pretty decent amount of rust at the lower door seams. I would like to repair/slow it down,

I have an 04 also and my doors are doing the same thing....I went to the dealer and they said it is not covered by the rust-through warranty.. I may try what you did to keep it from going through to the outside of the door. It really pisses me off that a 6year old truck is having this problem.

 

Not covered or the warrany is out. It started out in 04 being covered.

 

 

my warranty (6year rust through) does not run out until mid November. I was told by the dealer what GM means by rust through is a hole rusted all the way through the sheet-metal.

 

 

That's exactly what my dealer told me about a 2002 Bonneville I once owned. That's a bunch of BULL SHTI (sorry haha) I ended up having the hood repainted at my expense.

 

How does Tommy Boy say it??? Bulls Ass with a Butcher's head in it!
