I use propionate for protoypes. Can go in the water in a couple of hours.
I use etex for sealing. imo, epoxy is superior sealer because you get durability + sealing. I personally thin a bit with D. Alcohol then poor on and in to plug for 100% simple and easy coverage.

Regarding Propionate, if you want crazy penetration and durability, put plug in jar, close jar and leave over night (jar of prop. I use 1/2 gallon mason jar). The next day, take plug out and you can wipe off excess if you have very thick solution. In a few hours you get the acetone evaperaoted and you are left with a hard penetrated covering. You do NOT get this doing these quick dips that most people are doing.
I still prefer etex though for sealing, even with a organic respirator, I prefer to not be around acetone fumes if I can help it.

Some of these old school methods, that are pretty common, I shy away from them because they do not add to durablity. That is just my opinion though.
- blo/ms, valoil etc.
good luck guys
