RE: Acetone or denautured alcohol??
I use acetone and have had no problems at all. For about 7 bucks you can find out for yourself with a container of each.
Does nothing the the bond in any carbon shafts I've used and I stick the whole end in the can for at least 5 miniutes. I also refletch often. I don't think you'll find any shaft maker poh pohing acetone. Ask them.
