What is the best way to remove undercoating?
 

I'm getting ready to work on the underside of my 72 442, What is the best way to remove undercoating?

My car was completely torn down, had it sand blasted. Turned out very nice.....took all the rust, undercoating and grime away.

just had the bottom of my 55' chevy done. Took away 99.3% of the grime and undercoating...:thumbsup:

I had to use a propane torch to heat it up a bit then it comes off like butter. Then I used paint thinner in a spray bottle ( after and separate from torching :D ) let it soak then wipe away with lots of disposable towels...the blue or paper ones. It is a lot of work but turns out well. My media blaster said the media won't remove undercoat.:rolleyes:

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.

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

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

Thanks for the replies guys....looks like another messy project.

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.
