What is the best way to remove undercoating from my 69? I HATE THIS STUFF!!!

When I did this with a 69 Camaro years ago I used a heat gun and a scraper. Not fun at all for sure.

Brake cleaner will loosen this stuff up to where you can wipe or lightly scrape it off.

Thank you for the reply Don. I wonder who invented UNDERCOATING.

The same people who decided it was a good idea to load the roads with sand and salt during northern winters.

Eastwood makes a product that works really well, don't remember the name of it but it is on their web page. I have some left in my garage.

THank you for the reply. I did not think of brake cleaner. It is great stuff. It cleans everything

I found a local detail shop with a lift and a steam cleaner. For labor cost, they put it up and blasted all the factory undercoat from my 66 Bonneville. In hindsight, I should have left it there. I'm still patching holes in the floor pan that the undercoat was covering. http://www.chevelles.com/forum/smile.gif Actually, I'm glad to have found the holes so I could stop them. I think my total bill was $55; about an hour and a half. The downside is (if you want it spotless to paint or something) that they sometimes miss little spots or can't get into some areas. I take my winter-use cars there once a year in the spring to get the salt blasted out. My 96 Impala SS looks cherry in PA for the amount of salt it's seen in its 70k miles. Its was my daily driver until last month.

From my POV if you want to mess with it all day and do it yourself, Don_lightfoot nailed it. Get a small propane torch (a plumbing one from home depot will be fine) and scrape away. I would Put bags in buckets for easy removal and also, trashcans get heavy.

Good luck,

PS, I'm starting to like the sound of Curtis' method. If I can find a shop I think that's what I'll do on the velle. Undercoating is not fun to mess around with, real PITA.

A heat gun and a body rotisserie. It's a stand up job http://www.chevelles.com/forum/biggrin.gif

When I stripped all of the undercoating off of my 66, I used a heat gun and found that it worked better heating the panel on the inside of the car (interior). I propped the heatgun up using a couple of old brake drums and when the panel was warm, I scrapped the stuff off of the other side. When it was all off, I cleaned the surface with laquer thinner and painted with Eastwood's Corroless and Chassis Black. It's still a tedious job, but the results are worth it. This method is only useful if your interior is not installed. You can see some of my underbody pictures on my web site.

Really Toxic, but I used some Paint Stripper, this stuff gets expensive, but saves time..

I tried a paint stripper called "Safe-Strip". Came from Wal-Mart. It's not as toxic as most strippers & does NOT contain methylene chloride like most of the other ones. It looks and smells like Go-Jo "Fast orange" & can be sprayed with a plant mister.

Actually I havn't stripped all the undercoating off, but only a square foot or so just as a test. I let it set overnight and the undercoating scraped off very easily. I'm sure when I do all the undercoated areas there might be places that need a second application but as good as it worked on my test area, that won't be a big deal.

I don't think this stuff is quite as aggressive as Strip-Eze or Kleen-strip but it does work & it's not as toxic, which makes it the best choice to me.
