I'm getting close to putting color on my Coronet, actually yesterday the trunk & bottom got sprayed... It will be Delstar acrylic enamel which hasn't been available here for fifteen years so I can't run to the paint store & grab a "P"sheet.. But I have talked with a couple local painters & they tell me I can reduce it with DT870 reducer which is a urethane reducer.. I intially questioned it but the man at the painter supply confirmed it so rather than get reducer from out of state I bought the 870... This stuff is flashing off so quick it won't hold a wet edge to blend to... I'm thinking it's gotta be the reducer.. Any thoughts?? Thanks!
