This all good information. I definately want a sealant, one that lasts.

I'm going to look for some of the one part polyurethane products mentioned.

No one recommends Lexel?

I'm not even sure what it's classified as but it seems to be real sticky.
When cured it feels very rubbery and stretchy. Not sure of the longterm use
since I moved.

Thanks again for the info..
