Polyester Primers

I like to use Epoxie first for the adhesion to bare steel, then while the epoxie is still in the recoat window (24hrs) spray the featherfill ( no sanding). I used a 1.8 tip and it sprayed great. Block with 150, then prime with 2K, then 320 dry, then 500 wet. guide coat between each step..

I'm with Tin. The featherfill sprayed great with a 1.8 cheapie primer gun. The first few blocking passes can be real gummy if you use greater than 180 I found.

Btw, I try to remove as much featherfill as possible. 3M Drycoat is your friend :)

Hey Tin do you use a sealer coat of epoxy (reduced 1:1:1) at the end before BC/CC? Barry at SPI suggested it for good chip resistance.
