Tiny, tiny air bubbles in clearcoat...
What makes little tiny air bubbles dry in clearcoat? I sprayed my engine block today and it looked sweet..... but now i see tiny air bubbles that dried in the clear. It didnt look like that when i sprayed it, but after drying for several hours i noticed it was covered with tiny white looking bubbles.... you can kinda feel them..... what happened?

They are really small air bubbles.... kinda looks like someone sprinkled salt in the clear or something.... kinda feels like it too. You gotta be really close to see them.
I was thinking..... its not like this all over the engine.... just on the front and the top on the intake.... the sides and back are still really slick..... i sprayed the clear until the gun ran out completely..... and im sure as i was using up the last of the clear i sprayed it on the front and top. Can spraying the clear until the gun runs out produce bubbles or something? It didnt look like this when i first sprayed it yesterday, unless i just didnt notice it because it was still wet?
I tried to take pics from several different angles to show the air bubbles, its hard to see them, but you can tell theres so many that it kinda gives it a milky appearance.... you can really see them in this first pic on the front of the intake across bottom lip where the clear was thick.... and on the other pics, what looks like microflake.... thats the air bubbles.....
Let me know what you guys think. It really doesnt look that bad, im just picky.... should i just leave it alone, or how would i go about fixing it? I mean, its not like its a flat surface where i can sand down the clear.... and once i get everything on, it will be less noticeable.... but if i can fix it, i would like to.

Yea, the front and top were getting the sun.... you can tell by the shadows in this pic. Maybe thats what happened? I let it sit just like this for about an hour after i was done before pushing it into the garage.Originally posted by show-bound+Sep 26 2006, 11:40 AM~6247023-->Ahhhh, i understand what you mean now.

WHICH SIDE WAS FACING THE SUN....BET IT WAS THAT SIDE...
IF SO IT GOT PRETTY HOT/ ATTRACTED THE MOST HEAT....SO THIS AFFECTED THE THE CLEAR BASICLY MAKING IT BUBBLE BLISTER...
RESIN/HEAT =BUBBLES
YOUR CALL ON THE WET OR DRY BUT SINCE ITS THE ENGINE I WOULD USE DRY...220 WILL GET IT DOWN FAST...FOLLOWED BY 400.....LET IT SIT FOR A BIT HOWEVER...THE HEAVIER AREAS ARE PROB STILL WET...WHEN SANDING WILL GUM UP....
