Re: [Chevelle-List] Undercoat

[Keith Cooper]

I used a Sander/Polishing grinder which I purchased at Sears. I put a course wire wheel on it and wire brushed the undercoat from my trunk area, wheel wells etc. In tight spots I used a die grinders with a smaller wire wheel. This is a very dirty job and way to remove the undercoat but it works. You must be careful with the amount of heat you can generate using a wire wheel. I would also be careful with the heat gun. If you have to remove undercoat from the side fender area, you could blister the outside paint and mostly warp the fender panels. This would be the same problem you would see if you sand blasted the outside paint off. If you generate too much heat the panels will warp. Be careful not the generate too much heat. You might try a paint removing solvent, something that you brush on and let it loosen the paint(undercoat) so you can scrap it off. I am not sure if it will work on the undercoat, but it would not cost too much to find out. I think that the stuff that Eastwood sells for removing undercoat must likely is something that will loosen it up and then you scrap. Try some paint remover. Also, I think most automotive car paint store sell something like this also.

The heat gun I bought at Sears. (Paint dept.) The putty knife, well, what ever works.
