Rust Proofing

[brandon_guzzo]

I am having my new silverado under coated for the first time this year with a krown no drip formula and was wondering that after it has been rust proofed should i still wash the under carriage during the winter? I wash my vehicle about once or twice every two weeks int he winter and am not sure if washing the undercarriage will help prevent the salt from forming rust or should i just leave it. Also i would like to know whether or not it is better to park truck in the garage or outside again t help in preventing rust formation. Thanks for all the responses in advanced

p.s i live in the rust belt area of toronto

I've used similar products to this. During the winter, I have washed the under carriage to wash the salt off. I haven't noticed any of the rustproofing coming off, but I admit that I took it easy with the spray nozzle and didn't blast any body part too hard. The rust coating stood-up just fine to my maintenance. I can't comment on garage vs. outside parking, since I don't have a garage.

If I'm not mistaken I think that the rate of rusting increases with temperature. So if your garage is heated and the vehicle warms up overnight and all the salty slush underneath melts, it could increase the chance of rust. But with that undercoating, it should be fine for a number of years. I had that treatment done on my truck as well but at the dealership I bought it from.

 

I think you'd be better off parking in the garage just to lower the number of frigid cold engine starts.

I never knew Krown had a "dripless" formula, I believe it was them who stated if it doesn't drip then it doesn't run and if it doesn't run then it won't creep? (into all the seams and joints, where rust starts?)

Just curious why you are going with the dripless, I have used Krown and Rust Check regular stuff for years and yea it does drip/run for a few days but I know it is creeping/running in all those critical areas.

Not trying to be a smart ass, obviously getting some type of rust proofing is far better than nothing at all, especially for us who live in the areas we do but I do believe the runnier stuff would be a better choice?

 

Also, the best time to get rust proofing done is in the warmer months, lots of people wait until the fall/winter but with the colder temps it doesn't run/creep as well imo.

 

On your question, yea definitely spray the salt off underneath during the winter, especially when it gets warmer outside (Salt has no effect in severe cold but becomes very active in warmer temps, like said above) I have sprayed under my fender wells and other areas will no ill effects, it is near impossible to remove with just garden hose water pressure.

Also make sure the place you choose does a good job, I believe Krown is "suppose" to be a slightly better product but the place I went twice was terrible at applying it, way to many dry spots when I brought it home.

With my new truck I went to a recommended Rust Check dealer on Bloor St in Oshawa and what an awesome job the guy did!! I couldn't find any dry spots and just watching him apply it, I knew he was getting it everywhere.

I under coated my old Tahoe for years and if def. made a difference on the rust control. i did rinse off the wheel wells and underneith about once a week as well and as long as you dont get right close with the pressure washer its fine. I undercoated my new seirra shortly after getting it so that it would have time to seep and get dust covered before the winter comes along.

 

I have been told the that if your garage is heated its best to leave your truck outside and just plug it in, the change in temperature all the time just creates condensation with leads to rust.

X2 on that, my buddies and I use to spray our own vehicles for a few years, we would purchase the 4LT jugs of Rust Check from Can.Tire or a Rust Check dealer and shortly after we were done we would drive down a dusty sandy road north of my buddies place.

Doing that made a big difference for the external parts such as frames, diffs etc imo.

 

If you were able to rub the dust buildup on the frame, you would still be able to see the factory paint, it was like new underneath there!

A friend at work once said, (after someone said rustproofing was a waste of money and time (yea it takes all kinds) where can you get a $100 dollar body job? It is money well spent imo and it most definitely will increase your resale value!

Yes crown does offer the no drip formula but the main reason why i am going no drip is because it is only an extra 30-40 bucks which if it last longer who cares then lol. The no drip is heated to a very high temperature and sprayed on and it runs for about 30 -40 mins but after it has cooled off its not supposed to run but is still supposed to keep the metal protected with a thick layer of oil
