I sprayed my lower on my preban with Duracoat to match the original SP1 upper I had and it's been perfect for well over 5 years. That Duracoat process is easy and works just as advertised. Just follow the instructions and send your wife away for a few hours when you clean and heat the lower before finish.
Duracoat does offer a good match to most typical black uppers. And, no,duracoat is not reactive to brake cleaner, nor any oils.
