Last fall (2012) I completed the body work and primed the entire car with SprayMax 2K Epoxy Primer. Sanded and blocked with 400 grit.
I’m getting ready too spray high build primer in preparation to final block and ultimately spray color this weekend (May 2013).
Do I need to “re-sand” the epoxy primer before spraying high build primer, due to the long time (6 months) since blocking? If so, what grit would be best?
