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.

Can I start by saying that I am not a paint sprayer and this is based on trial and error

Carbon can be a tricky one to clear coat compared to say a steel panel. Good point made about the resin not being fully cured, presuming you have access to a booth/oven I would put the part in there for a good few hours to fully cure first.
 
I use Infusion but often clear coat parts to give UV protection, but this should also apply to skinned parts.

Wet Sand with 320's
Wash part thoroughly with warm water.
Dry in oven or use hot air gun on smaller parts.
Panel Wipe
This is the part I have found to be the key one. Wipe over with Plastic Primer (twice) spray applied on larger parts.
I use 2k clear starting of with 4 or 5 very very light mist coats, just to seal the surface. Allowing 15 minutes between coats to flash off.
Once the surface is sealed I then apply heavier coats until the required gloss is achieved.
I know this may not be "text book" but it works for me
