Hi im looking at geting a vacum pump to use when carbon skinning items. If i was to use when applying the carbon to the basecoat would i get away with just using release film? or will the bag material

work just as well?. Its just to get the carbon to stick properly on all edges to basecoat before removing from bagging and doing flood coats of resin.

Hi there Matt,
Sorry to highjack this...
So basically from what you're saying we dont need a release film unless the epoxy wold go through the part is that correct? Now, do we need to do a foam support for the part of just the part placed in the bad would do (given that the pressure would push the CF onto the part very tight.
As for the base coat, I guess sanding the part down (and if it turns black) should be enough..I guess.
What would you recommend to get this done?


I am interested in getting a pump. Could you please contact me at your earliest.


No, he means that the bagging film will release anyway.
You don't need any support, as the vacuum will create even pressure throughout the surface of the part, including the reverse side.

If you have an intricate part and feel the need to vac bag it, I would hit it with a black primer, then carbon with spray adhesive, then vac, then clear.
