Is TCP Global restoration shop base coats worth using or should I stick with Cromax Chromabase? The color is going to be Acapulco Blue going on a 1969 Mustang. I have used both brands painting road bikes but not a full car. I am using SPI Epoxy and clearing with Universal Clear. This car when finished will not see much sunlight, it has only put on about 400 miles in the last 33 years. Thank you for any replies.
