Suggestions on Undercoat
Posted by: gregb ()
Date: November 19, 2017 09:10AM

We are working on the Lakewood and I am cleaning up the underside of the car before the suspension goes back in. On the painted surfaces I am just cleaning, sanding and repainting but the fender wells still have all the factory undercoating and it is intact and in good condition but looks bad! Does anyone have a method to clean it up without removing it as I do want to keep it but improve its appearance.
Thx

Other than cleaning it up and spray painting over it not really.

I was able to use a heat gun and a scraper to warm up the undercoat and fill in some cracks. It was tricky, too hot and the coating bubbled or burned. Plus I was afraid of overheating the metal under the coating. After trying to smooth a couple of square feet I decided if I was going to that much trouble I might as well scrape it off. I directed the heat onto the scraper blade not the body metal.

A detailers trick is to spray Tire Wet (normally used on tires to make them look clean and wet) into the wheel wells to make them look clean and black. I periodically spray my wheel wells down with warm water, then when dry or just when detailing spray Tire Wet up there and I think it makes things look blacker and fresh.

If the undercoating is even remotely "lifting" on it's edges,or somewhere in between... Get rid of it and start over. Its a rust trap if it has.

If the undercoating is intact you can resurface it with a product that will look just like the original undercoating and will seal it to keep water out.

Not cheap but works well. 3M Body Schutz (correct spelling).

It comes in different applications, but I bought the reusable spray gun (no cleaning as the tips are throw away and come with the cans) since I was doing the underside of two cars. Wear a face mask - LOL.

Body shops can order it, but sometimes the Amazon prices are better.

Why not purchase a couple of aerosol cans of spray undercoating and freshen it? (after thorough cleaning of course)

If you use the aerosol cans of undercoating - test them first. Some brands are junk that won't hold up.

Maybe some ideas from my experiences with the Firebrier, which begins here.

I had not consider removing it because it appears to be in very good condition still but just looks bad is all. It is also only in the fender wells, no place else.

Use Rustoleum Satin Black to freshen up its looks. I'd on mine.

I've also used the tire-foam cleaner with great results.

I think I will give the tire shine a try first and see how it turns out.

Heck Greg I would just paint/rattle can using CLEAR. Whatever finish you apply will go away in a few blocks of driving anyway. Watch overspray on wheel wells but the underside will just be shiny. Good luck whatever you choose.

I was curious about the same thing before I️ put in my suspension. I️ thought about spraying over the original undercoating, but there wasn’t a way (I️ my head anyway) that I️ could clean 50 years of AZ dirt before spraying over. I️ took off the old undercoating with a heat gun and chisel. There is no easy way to do it. Time. Muscle. More time. I️ reapplied with 3M undercoating. It looks great and am happy with the outcome.

I remove it from all of my cars and repaint with epoxy. Its easier to care for and does not trap rust under.

Another county heard from...

If you are absolutely certain that no rust lurks under the undercoating, I have simply refreshed the existing with more of the same; in this case, an asphalt-based spray-on coating. Its authentic and quite effective when used properly.

However, if there is any doubt, clean it all (heat, putty knife, and a Makita) and apply paint on the bare metal before re-coating with asphalt base.

Just a thought...

Paint it, don’t remove it. When i looked into documentation on this, this
material contains asbestos.
