Okay so I'm having a couple of issues when skinning my parts. the first issue that i had is that I'm getting clusters of bubbles on the part but they are not carrying across the whole part. I am mixing my resin and allowing to 5 mins to de-gass i then cover the part with minimal resin and then go across the surface with a heat gun to try and eliminate any surface bubbles. 

The next issue that i am having but haven't got any pictures of it... I am finding that the carbon fiber is lifting when i am applying my first coat of resin. I have tried using a little amount of resin and i have tried using a large amount but in both cases the carbon fiber lifts as if it has a bubble underneath it. I have tried pushing it back down but it doesn't seam to want to stick to the part it just lifts back up. I have tried using the 'fusion fix GP spray adhesive' and i have also tried using the black skinning epoxy base coat, both with the same results. I don't know if this makes a difference but it isn't the whole surface that lifts its usually where a flat edge starts to meet a corner the flat edge will lift slightly (isn't bridging because its the outside of a corner not the inside) and it doesn't always do it in the same spot. 

Any help would be more than appreciated, thanks in advance Smile

Adding to the points above, it can certainly help to use the heatgun to lift the bigger bubbles.

It is a bit of a fine art to find the right moment to lay the carbon.  Too early is better than too late, as if you do it a bit too soon you can always wait until it tacks up properly. Some people find leaving the carbon in place for a bit longer before adding the clear resin can help too.
