Why is my paint doing this? (Pictures)

Soo I'm basically following the paint method in rattle can bling, and I laid my first 12 coats and it looked great. Then after letting it cure, I laid my next coats and they looked like this:

Could anyone tell me why this is happening and how to fix it? I tried a second time where i washed very well, rinsed with water, then used denatured alcohol, and it still looked like this...
 
Looks like it may be drying too quickly, as it's hitting the surface. What temperature are you shooting at? what's the humidity level like where you're at? Were you overlapping your passes properly and was it going on, wet?
 
I agree with RoadRash. I think it's called blushing and it is drying at uneven times. I'm not a painter I've just heard the term
 
I got of something like that by wet block sanding it down with 600 grit. Make sure you are well within the ranges suggested on the back of the can.

Sand until the color is even again and paint again.
 
Thanks for the responses guys. I've been painting in my basement and it has been about 72 degrees. Kind of humid though. And I haven't really been overlapping properly I don't think. It goes on wet and looks nice. But about 2 minutes later that stuff starts to appear.
 
Also, I'm using a dupli color metallic black automotive paint. That should be fine right? When it was warmer last week the paint came out looking great but maybe the temperature drop had something to do with it?
 
Duplicolor is picky. That is what I used for my tank. Had to wet sand the color coats then used 2k clear aerosol (expensive but worth it. It came out almost perfect. Check out my build thread for a few ideas.
 
Really? I used Duplicolor on my bike, and didn't have one problem with their products. My tank is done in VHT paint, which is Duplicolor, and it came out much better than I could have expected, with zero issues.

Hmm.....interesting....
 
I have used rattle cans for years on various projects. That looks like too much humidity to me.
 
The Duplicolor rattle can paints are lacquers. The lacquer thinner evaporates quickly and causes the surface to cool. If the humidity is high, and the temperature is near the dew point, moisture will condense out of the air onto your paint. I suspect that is what is happening here.
 
Yea too yumid...bruh. (thats lingo for all you NOLA guys who know people from Metairie, haha)
 
In the cabinet finishing business we call that blushing. Will almost always happen when lacquer is sprayed in high humidity and lower temperatures. The temperature of your paint can also be a factor.
 
Yep. It's water in the air getting trapped in the paint film. Had that more than once. If it's not too bad, you can sometimes get lucky and "boil" it out of the paint with a heat lamp but keep an eye on the temperature or you will burn it.

Try rubbing it with a clean dry cloth. Sometimes that will burnish it out if it's not too deep.
 
Hey guys thanks for all the responses. Everyone was right and I think it was a combination of humidity and the temperature of my tank. I heated the tank up with a hair dryer before painting again and it laid smooth with no blushing.
