Update: I tried a new clear coat on a classic car hood and it went cloudy

I was working on a '67 Mustang hood and decided to try that new UV-cure clear coat everyone's been talking about. I followed the tech sheet exactly, sprayed it in my booth, and hit it with the light. The finish looked perfect for about an hour, then a milky haze spread across the whole panel. I called the rep, and he asked about my booth's humidity, which was high that day. Turns out the product is super sensitive to moisture in the air before curing. Has anyone else run into this with the newer fast-cure clears, and what's your fix besides running a dehumidifier full blast?

Sounds like the product just isn't worth the hassle.

Yeah, that UV stuff is a pain with humidity. I had the same clouding happen on a trunk lid last summer. My quick fix was to lightly sand the haze with 1500 grit once it fully cured, then respray a regular 2K clear over the top. It leveled out fine. I mean, you really do need a dehumidifier for that product, it's not just a suggestion.

Totally get what you mean about the dehumidifier being a must. It reminds me of how so many products these days come with these tiny, easy to miss warnings that turn out to be super important. You buy something for a special job, skip one step because it seems optional, and then you're stuck fixing your fix. It happens with everything from paint to glue to those fancy cleaning sprays. The instructions are there for a reason, but they never make the big warnings big enough.
