ALEXSEAL® Super Build 302 is an epoxy-based high build primer / surfacer which
cures into a smooth easy to sand, water resistant coating.

ALEXSEAL® Super Build 302 has excellent spray characteristics and is fast drying
to allow maximum efficiency while fairing. The cured film offers excellent
mechanical resistance values.

ALEXSEAL® Super Build 302 is used to seal ALEXSEAL® Fairing Compound 202
and to even out imperfections remaining after the filling and sanding process. It can
also be used as a smooth, non-porous surfacer prior to the application of ALEXSEAL® Finish Primer 442 or Finishing Primer 401.
