Official Luthiers Forum!

Hey, I'm posting here, because there are more responses.
I'm going with a urethane finish on an electric I'm building.
Reason is, polyurethane is so hard.
I've got some Varathane spar urethane,
and would like to use it.
Is it a polyurethane?
It says for exterior use,
or, just for interior window trim, what!?
Anyway, anybody use this stuff?
Is it softer than poly?
I'm really biting my lower lip on this one.
Oh, I used minwax polyurethane on an electric, and like it.
Don't feel like buying ANYTHING at this point.
