Too much Clear Coat?
I just sprayed my tank, side covers, and tail piece and everything looked real good, i brought em inside the garage to dry overnight, and i noticed a few minutes later they started to turn a milky cloudy white color in certain spots... is this normal? i will take pics in a bout 10 minutes.. but does anyone know what im talking about? im really hoping i can just wetsand it and buff but it looks really disturbing to me...John 3:16Tags: None

My guess is either very tiny air bubbles or moisture. In your case, it is probably air bubbles in thick sections. You won't be able to buff those out. A key to spraying paint is to always make many light passes and not just a few heavy ones. ,BK

Ahh cold and damp not good.
The tank looks especially like it was cold and someone breathed on it and it clouded up with condensation.
I hope it turns out OK for you. let the parts cure in the conditions indicated by the manufacturer. I have had clouding in clear but not like that just along edges where it got a bit thick.

My guess would be that there was too much humidity in the air and it got absorbed after you sprayed.

How humid was it when you sprayed? How cold was it? How thick did you lay the paint on? And what brand and type of paint? I don't know if that's a humidity thing or not, could be.
I have shot paint with good results outdoors in below freezing temps several times, but the paint, the gun and the paintee were warm before the spraying, and I bring the items into the house as soon as it is sprayed. This was in a fairly dry climate but it worked OK.
Can't hurt to try to wet sand it out, if it doesn't work you will ending up sanding for a recoat anyway. If it gets rid of the cloudyness, polish it and see how it looks.

In my experience that hazy appearance will dissipate, although I've never seen such an extreme case. Worst case some will remain but hopefully, not much.Ed

Wet sanding will always leave a dull finish no matter how fine the paper, but it sets it up for polishing which really brings up the shine.
Did you use power tools for the polishing? Read post #26 on this other thread, by Darkstang:

did you use a rattle can clear? ive had this happen to me a couple times. i stopped using the rattle can stuff now. since then never had a problem, i go to an automotive paint shop and get custom cans of clear made filled with the dealer grade stuff.

You definitely want to spray wet coats. Really thin dry coats are hard to sand and to polish out, but that doesn't seem to be your problem. If it was above 70-80% humidty, you might've sucked the moisture in the air, right into the clear. That's what it looks like to me. Let it sit for a few days and dry. Take one part, say the side cover, sand it starting with 800 grit, 1200, then 2000. Hit it with a buffer, take it out in the natural light and see what it looks like. If it remains cloudy, you'll have to scuff it (and the other parts) with some 600, re-shoot the base coat and re-clear it again..in much lower humidity. Hope that's not necessary, but...1979 GS1000S,
