I have been using urethane primer for the last 2 years on a 56 Chev Truck project. I am down to rear fenders, steps and tailgate.
I have hated this primer from day one. I am sure I am doing something wrong. Mix as directed. I have even started adding some urethane reducer.
Went from 40psi to 30 psi, Opened the gun up some. Did about every thing that I could find on the internet.
I still comes out really rough requiring way to much sanding.
I used lacquer primer 20+ years ago and it supposedly will cause problems down the road.
I have bbw bbc fleetside 64 for my next project and I am considering going back to lacquer primer, how bad would that be?
Just shot some urethane on the rear fenders same old story.
