Re: Sealer
i sprayed a lot of single component sealers in the 80s, was sprayed right out of the can to give uniform color, could have minor bare metal cut throughs, non sanding. never a SW sealer. we used dupont sealer Centari AE SW base clear. Martin Sr. is correct. there are 2 components sealers spi has one in several colors 4:2:1 use just as you remember or 4:2, use as filling primer. or best yet an epoxy mixed as sealer gives great adhesion and a stable substrate.
