I have been looking for a few months now for a shop that can due undercoating repair and I have found none that does that kind of work. Even GM themselves don't due it anymore. They said alot of people r not doing it that much. So since I am having no luck on getting a shop to repair the undercoating I am wanting to see if I may be able to due it. Due you half to remove the entire undercoating or can I just repair it. I have noticed it alot around the inner fender wells on the front and the back of the car and along with the rear subframe on the car. Will undercoating paint by 3M fix my problem or will I half to find a shop to remove the undercoating and reapply it. Thanks

Just remove anything loose. Then clean it up and apply the undercoat.

Ok. What due I use to remove the loose parts and what kind due I get right off of the undercoating. I am seeing two different types of Undercoating spray. Rubberized and non Rubberized.

wire brush will work to get the lose stuff off. as far as undercoating the truck bed stuff works great in the rattle cans

Thanks but due I buy the Rubberized or the non Rubberized to redue the inner fender wells and my rear subframe.

the non ruberized will be a lot easier to hose off and clean the rubberized stuff will be like trying to scrub junk yard tires clean

So will any brand work or should I just use 3M only?

most any brand is going to be the same stuff different packaging. i use the generic stuff from advance auto

Thanks so much. I will put this on my summer list of things I need to due. I half to get body work and rust repair done first along with a new pain job.

Do, Due, Dew. Look them up. Also try half and have. And do let me know how the pain job comes out.

Seriously, the undercoating should be the non-rubberized and be sure to tape off all areas you don't want covered (including the driveway).
