I'd rather have it be complicated in the research process than later on. I didn't really look into shellac enough and since it didn't cure properly, it got more complicated than if I had just done it right the first time around. That's why I'm going through all the options now. Thanks for all the tips everyone.

I'm pretty sure I have found a US source for cashew. It comes in a BIG size that needs to be thinned so I'm going to have a ton of it if I do get it. If it works out, I will post here, because I will be interested in splitting the tub with anyone else who wants some. Dunno if I can ship it, though. I figure if it can be shipped to me, I can ship it, too. We'll see...
