What are the best application techniques for ensuring the durability and longevity of a heat-resistant top coat for resin projects?

The best application techniques for ensuring the durability and longevity of a heat-resistant top coat for resin projects include applying thin, even layers, allowing proper curing time between coats, and using a heat gun to remove air bubbles. Additionally, protecting the surface from direct heat sources and avoiding excessive heat exposure can help maintain the top coat's integrity over time.
