What about the filter-to-housing gaskets that are NLA?
Granted, I completely ignored Cardinal's question about the filter gaskets, and focused on the lid gasket…which he didn't mention. I went off topic… or kind of side topic, since he had mentioned powder coating the AC.
My filter gaskets were removed easily and I reused them again with new adhesive. They are strong, since they are solid rubber and I would imagine that most people will not damage them when they remove them.
But perhaps all of our filter gaskets may not be sealing as well as they used to, it is difficult to know for sure…and if they aren't, that would be bad news.
Maybe I'll try to find a replacement for those too… If I do, I'll re-post here.
