Gelcoat must be degraded to the same intake of food or feed, although using the gravity gun gravity feed gun would leave a more orange peel than necessary.
For the application using a suction feed spray gun will give you a smooth surface as the gelcoat is more finely atomized spray is throwing most of releasing solvent when spraying with about 60 pounds psi in accordance with a water separator, keep the gun moving to avoid the overlapping fold in the gelcoat each coat. heavier coat is applied over the micro pin hole will be, using a suction feed spray gun will give you a better quality finish.
Never spray gelcoat in the sun during hot days on the surface of the skin too quickly capture solvent to create a pin hole leaves a dull finish the job on completion.
