Guys I am going to have to get some base coat local (PPG) for my stripes on my mustang. This will be a custom mix so my question is SPI reducers and universal clear compatible with h PPG ?
You are under no obligation to follow my advice, but I would put 5% activator from whatever clear you use into the base. It doesn't "require" it, that is true. It just improves its adhesion and chip resistance.
