Snap-On tool guy wants to sell me a $500 Crud thug. Chemicals are expensive also plus messy and hazardous to my health. Any other suggestions to help save my sanity and arms from scraping?

It won't take everything off but most of it... Whats left use a propane torch & a putty knife & finally solvent & a rag...

I've tried every method there is, it's BY FAR the easiest and fastest! 200+ degree water, high presure washer = clean to bare metal (including some paint!). It's a wet messy job but it's eco friendly and suprisingly easy to clean up. 7332762-Hotsy.jpg (57 downloads)

Side benifit is that you can get a good pattern for your under carriage over spray and dip coat if you are going for a factory appearance. Sand blasting, scraping, and other forms of stripping will remove the factory finishes as well as the undercoating. 7332774-WheelWellsCleaned.jpg (80 downloads)

Factory appearance isn't important on this one. Its a 74 Satellite currently getting springs moved inboard. I have the car stuck in the garage on stands leveled marked for the install. Going to snag the heat gun from the shop and give it a whirl to see if its any easier. If not I'll hit harbor freight up for the needle scaler to give it a shot. I'm just concerned with the stories I've heard about their tools failing often. That one is cheap enough though where it won't hurt too bad if it does.

The needle scalers work but they will also chew up the surface of the sheet metal, sometimes pretty badly.....

Quote: The needle scalers work but they will also chew up the surface of the sheet metal, sometimes pretty badly..... they only chew up the surface of the sheet metal if your keep hammering away at areas that aren't brittle.... The needle scaler with cause lots of the undercoating to crumble but if it's still rubbery it will move around instead of falling off.... If it doesn't fall off easily you don't keep hammering at it, you move along knowing the next step will take care of those areas.... If you keep hammering away at it yes you will scar the sheet metal... Steam cleaner is great if you have an area to use it....

Sub-cool the area with dry ice and it gets so brittle it'll pop off, advice from this board a couple of years ago. R.
