Anyone know what seacast is . . . I always thought is was some combination of 1/2 chopped strand, cabosil, talc, and resin?

SEACAST POURABLE TRANSOM - LIST OF INGREDIENTS (100%)
Vehicle: Blend of proprietary polyester resins
Weight: 36 %
Solvents: styrene weight 18 % (CAS# 100-42-5 TLV 100pp)
Pigments & Extenders: (dry materials) weight 51 % - Titanium Dioxide (CAS# 13464-67-7), Calcium Carbonate (CAS# 14807-
96-6), Silica (CAS# 60676-86-0) and Inert Fillers (CAS# 14807-96-6)

It is a mix of proprietary resins and recycled ground fiberglass. You add the supplied ground glass then catalyze with BPO cream hardener. It is in my opinion only a good idea to use when the core is totally rotten to mush and the boat transom has a good existing laminate.

Seacast is a core material so you need a sufficient laminate on both sides of the material to provide the strength.

Proper preparation is key to achieve good results. They have a pretty good website with step by step instructions for use.
