Hi all. I'm getting ready to button up the oil pan on my '31 coach and was wanting to know how to properly use gasket shellac? I'm trying to stay true to the "old school" techniques, but haven't had any experience with shellac. Should I let it dry completely or just tack up before I apply the gasket? Should I use it on both sides of the gasket? Any info would be greatly appreciated.

Thanks again,
C.J.

Judging from the reviews and lack of posts I would think that few if any are using gasket shellac. I like to install gaskets dry and no sealer except maybe at joints or in this case a few dabs of adhesive sealer to hold the gasket to the pan. That way if and when you have to remove it again you will hopefully avoid a lot of scraping.

Only thing I ever use is Permatex #2. I only put a dab on the four corners of the oil pan. The best way to hold a gasket in place is to tie it through several of the bolt holes with a fine thread. The thread can be cut off after assembly.

i remember using shellac. i think we put it on one side of the gasket and the corresponding side of the block or pan, then when tacky put them together. a lot like permatex i think. i remember greasing the other side of the gasket after installation, then when you need to separate them you don't have the need for a new gasket always.
