Hi all , I seem to be getting a lot of tiny air bubbles appearing when I apply the clear coat, I am carbon skinning parts , I thoroughly clean and prep the parts, No problems with resin when applying, all seems to go very well , I spend a lot of time wet flatting the parts down and to be fair they look perfect ie nice and even , smooth and no visible signs of any holes or bubbles, I use a heat gun during resin coats making sure all bubbles are gone. I use acetone to clean the parts before clear coats, I really can't see why I am getting so many , although I am fairly new to carbon skinning ,I am not a noob when it comes to car painting ,I've been painting for 25+ years now.
Is there anything i am missing here.
Thankyou.

The reason I asked about acetone is that its pretty aggressive. I have used it in a pinch when I run out of my usual cleaner, but I have had some issues with it from time to time and it always makes me nervous.
