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. 

ALEXSEAL^® Fine Filler 303 is used to even out imperfections on appropriately prepared surfaces and can be used for surfaces above and below the waterline. If ALEXSEAL^® Fine Filler 303 is used below the waterline it must be sealed with ALEXSEAL^® Super Build 302 and ALEXSEAL^® Finish Primer 442.
