Hi, I’m using 3m performance spray heads (plastic) and I can’t find any solvent that will clean the epoxy out of them. I’m in California so not sure if that is the problem with the acetone/thinners I can gey. Any ideas? Thank you
If you wait too long, no solvent will clean it. Chris is right about what they call lacquer thinner. Some of it won't even clean base coat very well. The quality varies greatly. I give the guns a final rinse with urethane reducer, just to make sure.
