Gel coat

• Gel coat is a high quality resin that is pigmented with color and infused with additives that thicken it up and protect it from uv rays. Gel coat like all other resins requires a catalyst in order to harden.
  
  

Catalyst

• Gel coat is mixed with 1 to 2 percent methyl ethyl keton peroxide which acts as a catalyst for fiberglass resins. More than 2 percent catalyst can be added to speed up the cure time but never use less than 1 percent or the gel coat will not harden.
  
  

Application

• Gel coat can be rolled on, brushed on or sprayed on with a gel coat gun. Applying the gel coat with a spray gun is the best way to get a smooth professional finish.
  
  

Hazards

• Gel coat along with all other fiberglass resins generally gives off strong fumes that are known to be hazardous. A respirator should be worn at all times when you work with fiberglass materials.
  
  

Maintenance

• Gel coat can become oxidized from sun exposure. Gel coat can be protected from oxidation by polishing it with car or boat wax.
