Understanding High Build Automotive Primer

When I first dove into automotive painting, I quickly learned that high build primers are a crucial component.

I found that applying the primer in thin, even coats helped to avoid runs and drips. Following the manufacturer’s instructions for drying times and sanding between coats was essential to achieve the best results.
