This may not be your problem, but I changed out 3 pan gaskets thinking they were leaking and it was my dipstick o-ring letting fluid run down where I couldn't see it and running around the pan and dripping in the back, but to answer your question I bought my last kit from NAPA and it had a hard rubber gasket in it.
i agree, i also experienced the same problem. i replaced the gasket 4-5 times before i realized that the problem was the o-ring. but as far as a re-useable gasket, dont know of any. advance sells a pretty good rubber gasket in the filter kits, might give it a try. hope this helps
my last one leaked last week. we took it off and someone had torqued the bolts down and pulled the bolt holes in. we put the pan on a dolly and hammered it back into shape. i was told there is a gasket that has metal where the bolts go, but i haven't looked for it yet. if you need a thick gasket i'd check the pan for straightness first.
