Why Are There Small Bumps After Spraying Gel Coat?

Seeing small bumps after spraying gel coat can be concerning. This issue typically arises due to styrene evaporation, which increases the viscosity and causes the gel coat to form granules. While it can still be used and cured, the strength of the final product is compromised. Therefore, it is not recommended to filter and reuse it. However, if you choose to do so, it’s at your own discretion.
