My understanding of UV protections in a finish are that they are “absorbers” (this may be the same thing pontic described) and they do turn it into heat for dissipation. that is why they wear out over time in a finish; that might be slightly different than glass UV, my optometrist tells me that sunglass UV protection never wears out. That said, the finish should protect what’s under it, at least from the UV. The top coat with UV will have a longer life than those without it, but will still deteriorate over time….so yes, it helps with both (again, my understanding). Be aware, some comp[anies claim UV protection and may be stretching the truth (not GF). Flexner wrote of a UV test he did and Helmsman performed so poorly he concluded that while it was labeled as having UV inhibitors, it most likely had none….or so little it didn’t matter.
