Matt,
You are right, West 207 Hardener does contain UV inhibitors, but 205 (Fast) 206 (Slow) and 209 (Extra slow) Hardeners do not contain UV inhibitors.
So if you do use epoxy only make sure to use the 207 hardener.
I still think the System Three LPU is the way to go on carbon for clear coating.
I'm not moving to Santa Barbara. You got me mixed up with some other guy.
