Up until the Winter of 2003, I removed gaskets using blunt blades, careful application of razor blades, and constant worry about gouging the soft aluminum mating surfaces. But, while perusing an aisle at the local auto parts store, I picked up a can of Permatex Gasket Remover 80646. This stuff worked very well and made my life much easier. Essentially, I just needed to apply the spray, let it set for a few minutes, and rub off the gasket material with a rag or paper towel. It is a good idea to have some ventilation when using this product.
Thanks to Steve Payne for sending me this information in a private e-mail. In Steve's own words:
One solution I have had good luck with is using finger nail polish remover. It even comes with an applicator brush so you can get it into tighter places than the old aerosol cans. The only thing I don't like about it is the smell and how to explain to people why I have nail polish remover in my garage!
