PPG DZ-3 is a laquer thinned "high fill" primer. In other words it goes on thick & since it's cut (thinned) with laquer it dries almost instantly. It's way faster than used the tube type spot putty which I will sometimes use on large pinholes between DZ-3 coats. This stuff can add weight in a hurry so that's why I sand virtually all of it off. Once I'm happy with the hull it gets cleaned with PPG DX330, dried, shot with PPG DPLF white epoxy primer, cured for 48 hours, wet sanded with 600, cleaned, dried, then PPG Concept color. Another 48 hours then wet sanded with 600, thoroughly cleaned with 330. After the 330 has flashed off completely (about 30 minutes) graphics are wet applied, allowed to dry, hull is tacked, then clear coating begins with PPG 2021 clear, typically 4-5 coats. After 48 hours the clear is wet sanded with 1000, then 1500, then 2000, cleaned, then polished & waxed & boat is assembled. Alot of work but I want Concours quality results & anyone who has seem my scale boats in person can tell you the extra work pays off. B) B)
