Primes and Seals Substrate

ChromaGlast™ #5052 Gray Epoxy Primer Sealer is a first-class undercoating designed to protect composite and metal substrates while providing excellent paint adhesion and consistent color. This premium formula is easy to mix, easy to spray, and fast drying. It is compatible with properly cleaned ­fiberglass, carbon fi­ber, SMC, and Kevlar using polyester, vinyl ester, and epoxy resins. It can also be used with aluminum and carbon steel, but must be primed immediately after sanding. Our primer can be used with new work or repairs with a formula that is trusted by OEM manufacturers worldwide. ChromaGlast™ #5052 Primer features a low 2.1 VOC (max).

The #5052 is for spraying only on smooth surfaces that are otherwise “ready to paint”. If you need to resurface your substrate, try our #5060/62/64 ChromaGlast™ High Solids Primer Surfacer and Sealer.
