Awlgrip Painting & Overruns...

[BuilderFL]

I sprayed (HVLP) the repaired center console and T-top this afternoon and had a few paint overruns. Regardless of the fact that it hasn’t been more than 4 hours since I finished and it just started to rain on my new paint job…does anyone know if after only 12-14 hours of curing, it’s safe to sand the overruns and repaint? Thanks!

not knowing what the temp is, I would err on the side of caution and let the paint cure a little more before sanding and repainting

Today's temp was about 78-80 degrees. It's now about 73 and has stopped raining. I've got to return the compressor on Monday by 8am.

the last two awlgrip projects i got into were set back by dew. both of them had flat areas, luckily they happened on Sun, so it was teh following Sat before I resprayed. the Awlgrip maual( just happened to have one handy) says to allow 12-14 hours between coats, couldn't find anything about repairs

Not having used Awlgrip, I would expect it's like most paints. Until fully cured you should have the problem of the paint gumming up on the sand paper, a usual way around this is to use waterproof sandpaper and wet sand the runs by dipping into a bucket of water and block or hand sanding.
If the runs and blushes aren't too severe you can buff to shine the problem areas.
During periods of high moisture in the air, the addition of a retarder will stop blushing but make sags and runs more prevalent also increasing the drying or cureing time.
If you have never used a retarder, it was intended to keep the paint wetter longer on the surface due to drying too quickly while painting in excessive heat.
