2. Application gelcoat over mold
Most recommended for execution gelcoat fiberglass parts is gelcoat translucent isophthalic with neopentilglicol, it has a good toughness, very bright, high resistance to marine conditions, and does not absorb water. Usually, it uses white pigment.
Gelcoat is ready for use after adding the percentage of hardener (methyl ethyl ketone peroxide).

4. Lamination
The first layer of reinforcement layer is stratimat 300 g / mg powder. Be applied after the gelcoat has hardened layer (between 30 min and an hour, but no more).
Resin applied over gelcoat spray strengthened by your age or with a brush, roller or lamb leather. Should apply a thick and smooth, if it can double in weight over ranfort. The first layer of resin and fiber moisten be pressed to follow the contour model without double layers, cuts or scratches.
