No, Kip. They should be fine as is, and you don't want to risk messing up the tapers at all. At least you know you've got a good, sharp tool.

On the points themselves, I like to wash them out with acetone to get the preservative oil out of 'em and wrap a piece of 80 grit sandpaper on a tapered shaft and rough the inside up some, then rinse 'em out again. Sure helps the hotmelt glue hang onto them a lot better.

I've spray painted crowns before and finished them off with poly, but never have dipped any painted shafts in gasket laquer. I'm waiting to hear your report.
