Or you could buy a harder timber to start with...If slathering it on lberally does not do the trick, I'll try immersing a chunk of paulownia in a plastic bag full of the stuff and leaving it overnight. That would be extravagant with most products, but this stuff was less than $5 for a half pint. At that price, it I could put a guitar body in turkey basting bag with if it looks like it will work.![]()
