Looks great as I finish applying my UV resin with surfacing agent. Turns from nice smooth to orange skin! Too much or too little resin???

My guess is that you're using too much resin. Resin shrinks as it cures so if the film is too thick it will "pull" itself into that characteristic orange peel pattern. Be careful not to over react and make it too thin or you'll have a different problem -- improper surface cure (not enough wax).
Hope this helps,

Ya know BB, I have had that same thing happen with UV hotcoats. I don't use the UV for hotcoats anymore unless I'm really in a hurry. UV for just lamination. What I think happens is that not enough time is given to let the wax rise. You run the board outside, it kicks off with the wax in altered states, and you end up with this brain pattern on the deck of your board. When I use the UV hotcoat I make sure that I kick it off slowly with just a slightly opened garage door, or window for some UV. After it's had a chance for the wax to rise, and slightly kicked for, errrrr, let's say 10-15 minutes, then I walk it outside and bake for a 20 second shot, and walk it back into the now wide open garage.

just my 10 cents on what happened?

It is too wet. Use less resin.

Ditch the UV for the hot coat. BUT if you must here's some advice.

Brush it on and then let it sit for a few minutes. Open up your doors to let the UV light in but only ffor a minute. Then close the doors (or take the board out of the sunlight and into shadow) Let the board sit for a nother 10 minutes and then expose again to UV light for a nothe 2 o three minutes and then take back into shade.

If the sun is not so bright then add a little bit to each step.

With UV resin you have to let the wax rise before you expose it to the UV. Otherwise there isn't any surfacing agent on the surface and you get orange peel, surface tention. In the summer in FL we used to have to add wax on hot days to regular hot coat resin because the resin would kick so fast the surfacing agent didn't have time to rise.
