richie916 - Gasket Laquer is a type of nitocellulose based laquer. Home Depot carries a variety of it - only $16 a gallon, however I have been warned that it does take 2 for 1 coats as its not nearly as thick as the Gasket Laquer is. These types of laquers are used on penciles and guitar finishes to name but a few uses.

Personally, with help from everyone here, I spray paint my shaft, crest it, dip it twice in Minwax Polyacrylic (to preserve the crest - GL will eat it right off) then dip 3 or 4 times in GL. That gives me a hard, gloss finish for my arrows. I then fletch with DUCO cement. Its THE best way I have found so far to do it. This is for aluminum arrows and carbons by the way - woods are a different game for me.
