Gelcoat  Waterproof

Basically gelcoat is the smooth colored finish on a boat. There are two type of gelcoat, Brush or Spray.  Brush which is very thick is used for repair or touch up work.
We care a large selection of 3M Compounds and Waxes  along with our low cost Rayplex line 
Check out our How to Buff your boat Video.

Brushes Chip inexpensive

Chip brushes are low cost and through away which save the expense of cleaning and the cost of solvent.
Use for laminating do not use for applying gel coat as bristles and prone to fall out.
Brushes Red are a little stiffer and used for laminating or the application of gel coat.

Fibreglass Tools

Gloves Latex gloves for protecting your hand from the resins and glass.
Mask High Quality 3M masks when only the best will do.
Matt For simple basic repairs we suggest using Matt which conforms to the surface.
Mixing Kit Includes mixing tubs and syringes for measuring Catalyst accurately.
Resin We suggest using our Premium grade #215 Isophthalic resin as its waterproof and safe to use below the water line.
Rollers  Our handy 3 in jr rollers are excellent for the application of resin and getting the air bubbles out of a laminate.
Solvents Acetone for cleaning tools and hands,  Air Dry or Wax solution for making the gelcoat dry tack free.
