Hey Ben

Might need a little more info......Sounds like your working with epoxy? Doesnt sound like paint

Are you whipping air into as you mix it??

I've noticed with some of the fairing fillers that they hold air a little more than some of the other fillers......
Also if it is real thick (which it may need to be on vertical surfaces to stop sagging) It will not flow as easily so air trapped will not surface.

For screw holes and such mix in some cabosil/collodial silica/west 406 .... you get the idea. Fill the hole from the bottom .... in other words dont fill it as if you were spackling a wall with plaster by just wiping epoxy over the hole. Force the epoxy deep into the hole and build it out ( If I can I tape the backside of the hole to stop it from dripping out).

As for having to do the second coat ....alot of times I need to go back over hole with more epoxy after fairing.

Hope this helps [img]images/icons/smile.gif[/img]
