How to Polyflake a Boat

A polyflake gel coat is a hard gel coating containing metal particles sprayed onto boats to attract certain kinds of fish, such as sea bass. The fish are attracted to the light reflected by the metal flakes and swim closer to the boat, making them easier to catch. Polyflake coatings are not difficult to apply, but require a large work area. Apply the gel outdoors on a clear, sunny day when temperatures are between 60 degrees Fahrenheit and 90 degrees Fahrenheit. Higher or lower temperatures can alter the finish by drying too slowly or quickly.

Things You'll Need

Liquid soap
Soft bristle brush
Soft cloths
Acetone
Plastic tarps
Sandpaper 400, 800 and 1,000 grit sandpaper
Polyflake gel
Gel hardener
Airbrush gun
Respirator mask
Safety goggles

Instructions

- 1
  Clean the surface of the boat with a soft cloth dipped in soapy water. Use a soft bristle brush to remove any stuck on contaminants. Spread tarps around the boat to prevent the gel from getting onto nearby surfaces.
- 2
  Sand the surface of the boat where you want to apply the polyflake, starting with the 400 grit sandpaper, then with the 800 and 1,000 grit sandpapers.
- 3
  Clean the surface once more with acetone and a soft cloth. Allow the acetone to dry one hour.
- 4
  Mix two parts gel with 1/2 part hardener. You can use more or less hardener, depending on how quickly you want the gel to dry. In cooler temperatures, add up to one part hardener. In warmer temperatures, use as little as 1/4 part hardener.
- 5
  Place the gel in the airbrush gun. Wear a respirator mask and safety goggles when using the sprayer. Spray the polyflake evenly over the surface of the boat. Hold the sprayer about 10 inches to 12 inches away from the surface of the boat. Spray just enough in one location to saturate the surface without causing runs or drips.
- 6
  Allow the gel to dry until it is slightly sticky to the touch. Spray a second coat of gel over the first. Allow the polyflake gel to harden for 48 hours before using the boat.
