It is a lot of work but turns out well. My media blaster said the media won't remove undercoat.

Heat gun and a wood paint stir stick to keep from gouging the metal for 98% of it. Wax/gease remover and a brush to aggitate the remaining residue.

I was looking for another method other than sandblasting. I just finished sandblasting the frame and will never do anything that big again, the mess is just too big.

Angle grinder with a wheel cup wire brush works pretty quick, just messy as all get up when you are underneath it.

This is the way I did. It gets you dirty, but you can do it in your shop when you have time and saves $$ for other car stuff.

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.

Have some one else do it, is the best way!

Tiger torch, scraper, welding gloves and beer is next best IMO.

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.
