Product description "Polyester resin"

Sea-Line® structural polyester resin is recommended for laminating, reinforcing the surface, and patching holes and damage – especially in situations where the most important is a fast repair time.
In conjunction with the glass mat, it is used for manual repairs of damage.

To obtain a fully-fledged and adequately strong laminate, use a 2:1 weight ratio of resin to glass mat for polyester or a 1:1 weight ratio of resin to glass fabric.To finish laminated surfaces we recommend using Sea-Line® fillers, Sea-Line® epoxy primers, Sea-Line® topcoats or a Sea-Line® gelcoat repair kit.
