Our Excel Autobody Products XL series of primers - urethane, acrylic or epoxy - offer excellent opacity, firm build and surface leveling properties, are fast drying and have great sanding properties. Or try using our direct to metal (DTM) primer that has superior adhesion to cold rolled steel, aluminum, galvanized, body filler, and fiberglass and can eliminate the need for other primers/sealers. Like our XL 370 2k urethane sealer that’s formulated to be applied as a low-build non-sanding sealer, it can be tinted with basecoat tints and has superb opacity for slick topcoat finish.
