Spraying Gelcoat and Awlgrip?

[abl1111]

There is always using Duratec as a 'thinner' added w/ the gelcoat. However, I am not that familiar with it. A lot of the pros use it around here..

It helps the spray lay down smoother.

Even with the use of Duratec as a thinner, a pressure pot sprayer should be used. Getting gelcoat down to a viscosity suitable for conventional spray equipment is risky. Many problems can be caused by over thinning gelcoat.
