I just recently joined "Moparts" and came across this topic. I started painting my car's under-carriage and engine compartment with "Tremclad" Black Satin with spray cans about 2 years ago and I want to finish it with the roller. It's been 4 years now, I Work Slow I am wondering if the Black Satin will Buff out like Satin or Gloss Also I was going to put on Silver Grey Stripes . I bought a can of Gloss Dark Grey and a can of Gloss Aluminum . Will the Two mix OK I guess I will find out One Way or Another
