Application

Series gel coats are formulated for spray application as supplied.
Thinning is not recommended. For catalyzation, use MEKP @ 2% for
gel times shown above. Do not catalyze at levels below 1% or above
3%. Apply in several thin overlapping coats rather than a single
thick coat. This will help avoid sagging, porosity, solvent entrapment
and other defects. Make sure the air pressure is adjusted properly,
and that the spray gun lines are free of solvent, water and oil.
Apply to a thickness of 18 - 25 mils wet. Brush application is not
recommended.
