Clear Finish

[McCreed]

First, apologies to a_novice for the hijack...

Water based poly urethane is more common. Just wish someone would come out with an automotive water based clear.

Rabbit, I've seen water based clear "lacquer" for guitars and woodworking. How would that differ from an automotive lacquer?
I'm just thinking vintage guitars were painted with auto lacquers, so wouldn't it work other way around?
FTR, I've never done any car painting and my only experience with lacquers has been on guitars.

Also, I've just been reading a bit about waterbourne automotive paints, and it does seem like the technology just isn't quite there yet. Even PPG, whom I think kind of came up with it first (???) points out its shortcomings.
