My runs tend to be in the middle of panels, I never stop my clear on the edge of doors or any panels to try to prevent buildup on edges. My runs seem to be where my overlaps are from the first panel to the second ( if that makes any since) I have been walking the entire side trying to prevent this and it has been helping but I think that I should be able to adjust my gun/spraying style a bit to help as well. But I have noticed the runs tend to occur more around the indentations of door handles/ locks etc basically where I have it taped off from the backside. I am going to try just keeping my mixture 3:1:1 and see how that does, I think that the extra activator is making this clear easier to run. And I am going to try to figure out what the panel temp is as well, this seems to happen more when the temp drops. Has anyone had any experience with those infared guns that tell you panel temps? I think harbor freight has them on sale this weekend. I want to get this figured out before it really gets cold here. Like I have said before it is a real challenge to keep heat in the booth while spraying. Thanks for the help folks

1.4 tip and cold temp = runs. Try turning up the heat in the booth and going with a 1.2 or 1.3 tip and i dont think you will have an issue any more.
A 1.4 in an iwata is like a 1.3 or 1.2 in a sata,not a real issue.Try some Lesonal accelerator in your clear,this will help it tack up faster,also make sure your first coat is hand slick before you apply your second.You can also turn your fluid control in a bit,but speed and distance will do the same thing.
Went in today and sprayed two jobs, used the rapid activator on both of them. No problems to speak of, decreased my distance to about 4 or 5 inches and picked up my speed and kept the mix at 3:1:1 instead of 3:1:1.5. I will try that for a few days and post back at how things are going, Thanks for all the tips. Its good to have a place to go to when you have to troubleshoot these things.

[quote=”Jayson M” post=22584]When was the last time your exhaust fan and stack were cleaned out?That could be all that you need to get some more airflow along with fresh filters.The universal is a pretty good clear(I swear it is re-packaged ACII) it can be used for small jobs or allovers,thicker than proair and nicer to spray.I don’t know it you can use ACIII hardener and activators with it but I suppose it is possible.[/quote]
pretty much is. If ever in a pinch on hardener and activator, you CAN use the ACIII standard hardener and activator. I think it buffs a little easier than the ACIII though.
Of all the AKZO clears, I beleive the Lesonal Universal is their best. Cost and performance.
Have you tryed the tack and whack method?? Your first coat is just a real misty tack coat no gloss at all then hit it straight away with a full wet coat. Tack coat helps the following wet coat stick to the panel and edges like door handle indents body lines door edges etc.. Also as jayson said increase speed a bit and distance wind your fluid in a bit too. We all get the odd run from time to time all part of it. Just like the beaters miss pinholes and dents :rofl

I disagree,not even close to their best clear, Universal is a decent crash clear and it is relabeled ACII,but it is a little skinny after it dries.I would rank it #4 after Superior 250,Lesonal Glamor Clear,HS +.I have sprayed just about every major clear there is including SPI and nothing comes close to superior in regards to DOI and gloss retention.
I can’t even remember the last time we used standrad hardener,we always used XP hardener in ACIII.Been using the universal with the sikkens activators for about a week now on everything, been trying different ways of spraying it and have gotten the runs under control, it has been a little warmer than it was a few weeks ago so that has helped. Still not real comfortable with it though, havent quite figured out how far I can push it but it will come in time. Noticed that the finish and DOI are much better with the medium activator and about a 1/4 ounce of accelerator in it than with the rapid activator. I did try to spray a light coat for the first followed by a full coat for the second and it left me with more peel than I would have liked. Nothing that a buzz with 1500 and a buff wouldnt fix, but I am trying to get away from the buffing as much as possible. But all in all it buffs way better than the proair that I was using before, and give it a little more time I think that I can get the peel the way that I like it. I have really noticed that it goes alot farther than the pro air as well, it dont need to be pounded on, I have to keep reminding myself that when I mix it or else I always have some left when I am done.
I think that my biggest challenge in the next few months is trying to keep the temps up in the booth when I am spraying, neither of my booths are heated and I have to rely on the building heater to keep the temps up. Thanks for all the advice and tipsChuck
