Hi, I have a rear diffuser for my TVR T350c in fibreglass. I have heard conflicting advice as to wether or not I need an etch primer before the the primer. any advice would be helpful thanks
etch primer has rust inhibiting properties, to etch to bare metal, so no, just prime paint and clear. You will probably need a high build or 2pack primer though, as fiberglass is notorious for not being paint preped.
