This is what I do. Wire wheel is what I use for the stubborn parts that I cant do with the razor blade. Just remember to clean the entire surface with brake cleaner before applying any sort of gasket.
If its an iron block and steel pan have at it with a razor scraper if its aluminum you need to be more careful.
Use CRC gasket remover on both surfaces overnight and scrape it gently so you don't gouge the aluminum.
Is that a surface prep or does it dissolve old gasket material glue, interesting product.
The old version was brush on, the bottle looked just like Gask-a-Cinch. It worked great at getting old gasket material off the intake manifold on my 95 Mustang 5.0L. I would apply it, let it set for a few minutes, and use a plastic scraper or razor blade and it would come off super easy. This is what they want our techs to use as the last thing on an aluminum surface before laying the gasket on.
This stuff works awesome as well. The tech that uses it says you just spray it on what you need removed, go off and smoke a cigarette, come back and just wipe it off. Obviously there are more productive things to do while waiting, but I don't judge.
