In Indiana, I have a lifetime permit. Once its issued more than 5 years, it will still be valid but they'd still run the check.
Of course that's if I understand the write-up.
I wodered what happen to the guy a few years ago asking about building a bridge. (That was a classic thread where the OP didnt want to listen to all the advice being offered) Now we know.
Ive only used Spar urathane on woods I've stained. I cantbreally say much about tone but it seemed to look about like normal polyurethane. Maybe just a little thicker coats.
Good luck with the move.
