I need to get some flat black primer to go on bare metal. Since primer absorbs water and can rust in the future, I hear it needs to be sealed for protection. I was looking on
www.eastwoodco.com and seen House of Kolor Kwikure Epoxy Primer & House of Kolor KO-Seal II Primer Sealer. Should I put down the epoxy primer first and then go over that once it dries with the primer sealer? Also, I see that there are options on the epoxy primer such as: Surfacer 2.1 VOC, Activator, Chrom. Free Pt.A, & Chrom. Free Pt.B. What do I need? Thanks for any suggestions.
