Yes, BlackTop bonds well over fully cured epoxy primer, DTM primer, and body filler.
Glossy surface? If the primer or filler is glossy or shiny, lightly scuff it with 320 grit before applying BlackTop for the best adhesion.
BlackTop applies directly over fully cured epoxy primers, DTM (direct-to-metal) primers, and properly cured body filler. Make sure the surface is dry and free of dust before you begin. If the primed or filled surface has a glossy sheen, scuff it lightly with 320 grit sandpaper first, since a smooth, shiny surface gives BlackTop less to grip.
