What is the best way to remove undercoating?

[GM Muscle]

i used an industrial strength, concentrated degreaser and let it soak 3 or 4 times and then went at it with a heated power washer.

this thing kicks butt for this job.

You can bruch on adhesive remover - you can buy that from home depot by the gallon. Just let it set for a while and scrape it off. Nasty mess.

If you have it on a rotisserie, then I'd suggest renting a power steam cleaner/washer. You can just blast away the undercoating/etc. works really well

Just tried a propane weed burner and plastic paint scrapers. Scraped off like Butter! The scraper eventually lost its edge due to heat so it requires 2 or 3 per wheel well. Finished one well in less than an hour. Best of all the the debris got hard again right away and swept right into a dust pan.

I use an air hammer with a flat edge. Chipped right off.

Got the hard to reach areas with a wire wheel.

They say this tool cuts through it like butter and is great......I haven't personally used one but I am considering the purchase of one for my cars......

After just finishing mine, I'll never not have it blasted off again. It takes to much time and is a total PITA, no matter how you do it yourself.

99.3%

The specificity of that just made me chuckle. I get what you mean, but it still made me laugh.

I did mine with oven cleaner, scraper, torch, wire wheel and power washer.

Mine was on there thick and hard... so I had to use a combination of stuff. What a frickin mess.

I spoke to the shop that was gonna blast my car and they said alot of undercoating is hard to get off since the beads want to bounce off it or just dent it in.... takes alot of time to get it all off. They could do it but it added quite a few hours to the job. So doing it myself probably saved me a couple of hundred bucks....but it was a huge PITA.
