What Is the Best Diluent for High Viscosity Polyester Gel Coat?

While gel coats are formulated to be spray-applied without any additives, it is essential to consider that the issue may lie in using the wrong spray gun nozzle size rather than seeking a diluent. Any form of dilution can alter the original formulation, resulting in less than optimal performance.

If dilution is necessary due to circumstances, it is recommended to use less than 5% styrene as a diluent instead of acetone.
