I am glassing a board for my son,and when curing out the gloss coat it became all wrinkled looking. I use suncure resin and my lam job and hot coat did fine. this was my first time doing a gloss coat.I am pretty sure that I will be able to sand it down and then buff it out, but it will be a royal pain. Any idea of what went wrong and how to fix the problem?
First off suncure gloss is a no, no. Why? well, you have to walk the gloss out into the sun or move the board. That’s how you got the wrinkles, you were slabbed. Also you need to give the gloss time to let the surfacing agent rise and form a nice slimy layer, suncure won’t let that happen again…you have to move the board and disturb the process. Gloss coats need to be done in a non air circulating, semi dust free room. You have to put it on just thick enough so it flows, but not so much that it will sag at the rails. Something like a pint of gloss to about 35 cc of cat is what i use, gel time is around 10 mins max. This gives you just enough time to gloss and close the door, clean the brush, get beer, walk back in, pull tape, and watch boogery gloss tape line blend in with other gloss line.
I’m a fan of lamination resin with suncure, pretty hard to screw that up, but even for hotcoats you can get slabbed, orange peeled, or the dreadded sandblaster with a dog hair spritzer in a hurry. it’s best not to move boards around when your in a chemical reaction state. Anyhow it’s just gloss, you could grind it off in 5 mins with 80 grit and do it all over again. All you’d be out is $5.00 in gloss, 5 mins, and 5 beers.

resinhead nailed it.
lose the suncure, go out and get some reichold gloss resin (if it’s available), mix it according to kokua’s recipe…and most importantly…lay it on and leave it alone. shut off the a/c in that room. don’t even walk by the thing…it creates a draft.
yeah, just use your power sander and take most of it off and start again. It’s happened to most of us 
I found out that my problem may have been not enough time after wiping the board down with acetone (aprox 3 minutes)
Moving board not a problem, I use a UV light to kick it off.
Any theories on the acetone being the problem?
I’m with Soulstice - any air circulation really screws a gloss coat - I won’t even walk past the board once it has been glossed until until it kicks in ! I don’t think that acetone is the problem.

A good gloss coat is something to be admired, but not as much as resinhead’s comsumption levels. Jeez, man, 5 beers in 5 minutes, and that’s while you’re sanding! Someday…
It’s all in the custom 3M mask, it’s all in the mask!
I didnt use the acetone on the bottom and it turned out realy good, sanded out the wrinkles all the way to a 1200 grit then buffed with polishing compound and the board finished out pretty good, lessons learned.
