been using the hok uc35 urethane clear, guess you can say im experimenting as i go along.. first time i did exactly as the tech manual called for, but ended up with orange peel, had the medium reducer for around temp of 75-80. it was around 9-10 at night , so that was a factor to consider, amongest other stuff.. well i did it again during the afternoon around 3. added about 2 additional ounces and decided to use fast reducer this time.
i got alot less orange peel, n it dried alot faster. also notice it came out better for me.
Has anybody messed around with this clear?
just wondering if i should keep added about 2 extra ounces of reducer n choose a faster reducer than my temp really is.
also have to consider i live on top of a mountain so i get a different atmosphere up here.
anyways will be using fast reducer from now on the way it looks to me. any ideas?? or inputs on this.

There are many factors in spraying that will effect the amount of peel in your clear. You can add about 10% more reducer to your mix for better flow out, or slow your reducer down, but the best way to get less peel is to lower your air pressure. Peel is formed from the paint droplets hitting the surface and bouncing off. It's best to stay with the reducer in the temp range of your paint area unless humidity is high. UC35 tends to stay soft when you try to build with it. Don't put on any more than three coats at a time. I've shot alot of it but I'm not a big fan.

your so right. i used a different psi air setting this time around n a little more reducer n fast reducer instead of medium, last time i had moisture in the air i could feel it, but i did move the gun slower last time than this time.. notice when i move the gun faster than i did last time, seems to lay it smoother. thinking i was a little to close and moving a little to slow plus humidity in the air.
there wasn't any humidity this time though. thanks once again you've helped me alot.. next time i keep doing what i did the 2nd time around, n take ur advice

well im going answer my own post lolol, all i did was added like 10% more reducer maybe a little more than 10 percent, but the temp was dipped lower than what i wanted it to be.. im using fast reducer for 65-75 i think... temp was like 55-58.. really sucks.. but guess i hit it with luck cause i got the clear pretty slick and has very very little orange peel, alot says dont buff but im going to go ahead n cut n buff it... considering i have graphic edges.
not suppose to paint under 70 or so hok suggests it, BUT i had no choice, i had to spray n chance it.. evidently i kept alot of heat lamps on at night to keep the colder air from coming in.. somehow it turned out better than i thought or expected.

Have you tried using KU100 as your catalyst? I find that since I switched my UC35 flows smoother and dries harder.

i went with a fast reducer forget what hok fast reducer is, think 65-75 temp and i sprayed it at a lower temp that what was recommended. it seem the weather slowed the drying process down but hence where i live thinner air.. it dried w/o any orange peel at all.. go figure.. so seems like img oing have to use fast reducer here at the new location where i'd moved to..
