My question id do I have to change the primer-surfacer acrylic type,and the bond-sealer (all Nason brand) if Iam going to switch to basecoat/clearcoat. From what I have been reading in all the post, is that basecoat/clearcoat is the way to go. Iam painted the engine compartment with acrylic enamel 2k urethane pewter-metallic gray. It came out alright. Iam using a sharpe fx300 with a 1.4 tip. Also used craftsman hlvp with 1.8 tip. So is bc/cc easier than the acrylic enamel 2k urethane for the rookie in me?
