Never assume a clear topcoat makes epoxy UV-proof.
100% solids epoxy gives you build because what you put down stays down — there’s little to no material lost to solvent evaporation.
That makes it a strong choice for the body coat when you need thickness and durability.
But here’s the mistake: epoxy itself can still amber from UV exposure.
A UV-stable topcoat can help protect the system, but it doesn’t magically make the epoxy underneath completely UV-resistant.
Know your products. Build the system correctly.
