Ideal to Fill and Fair Minor Surface Imperfections

ALEXSEAL® Fine Filler 303 is a solvent-free, epoxy-based filler which cures without shrinking. It cures as a water resistant solid coating. This is an ideal product to use between ALEXSEAL® Fairing Compound 202 and ALEXSEAL® Super Build 302 or ALEXSEAL® Finish Primer 442. Fine Filler 303 is used when a tight pull of fairing is required to fill small imperfections prior to applying a surfacer or finish primer.
