Re: Pcking a high build primer

"primer" bare metal SPI epoxy every time @K primer surfacer spi also has a couple i like their regular 2k. if you have really deep scratches and a lot of filler work to smooth out slick sand. always use epoxy on any bare metal for best adhesion and corrosion resistance.
