I'm new to all this so I first tried epoxy and had little luck with it (I've used it for years at work but never as a finish)
Tried the inexpensive Chinese UV product that Engineered Angler on YT talked about and first attempt didn't fully harden at first. Found out that was due to wrong light spectrum(?) in my uv lamp.
Changed to the proper (guess it's wavelength?) UV lamp (cheap amazon) and have had excellent results.
** I'm concentrating on visual quality and success rate of application here. Don't have enough time in (that and ice everywhere in MA) to test durability and longevity yet.
I figure like the above poster suggested, find a process that works for me until I can be assured of it giving the finish I require and can replicate easily. At that point, I'll feel comfortable figuring out the other aspects of the clear coat stuff.
One disaster at a time lol
