“Are there acrylic powder coats available other than a clear coat, and if so what is their advantage and major use? Also, can you suggest a primer that could be used to enhance corrosion protection and is compatible with a TGIC Polyester powder? Thanks.”

“Acrylic powder coatings are very hard materials and provide superior UV stability. Zinc-rich powder coatings can be a very effective primer for TGIC polyesters. However, I would investigate better substrates (Galvanneal) and pretreatment (Zinc phosphate) before using a primer. These (galvanneal & zinc phosphate) in combination can provide up to 1000 hours of salt spray protection on a scribed panel.”
