I've painted the cab, doors, and fenders on this truck and all has gone pretty well in terms of how the clear laid down. But the last few panels I did (hood, bedsides, tailgate) all came out with significant runs/sags. Same gun and settings, same air system, but temperatures were lower. I'm using a Tekna Copper with the 7E7 cap, 120+ at the wall, 26-28 at the gun trigger pulled, 2.5 turns out on fluid, and nearly all the way out on fan. I was moving 50-75% faster than usual as well and I still got these huge runs/sags. I had the bedsides laying flat and the tailgate hanging. I have trouble making the concave section of the tailgate come out nice due to that contour.
First question - how do I fix this? Is it worth using a razor blade to scrape the highs off and then 800, 1500, 3000, 5000, then polishing steps? Or should I just sand it down and respray? I can take the tailgate off without too much trouble, but the bedsides are installed and they're a lot of work to take back off.
Second question - is Euro or Production clear less likely to run or sag as they are not high solids? I'm thinking I would rather use those clears as I don't do any cutting and buffing as I've been happy with the results straight off the gun up until now. It would also be nice for the clear to more scratch resistant sooner.
