As mentioned..   3x not a charm here.

I have this isseu every time.
Clearcoating without gelcoat would be an option. But allso that isnt easy with small holes like this.

Now i used gelcoat. Hoping it would help.

Gel had cured at 25 degrees for 5 hours was dry to touch.

I used 3m high tack clear spray adheasive to hold the fibers in place. (AS LITTLE AS POSSIBLE)


on the vacuum catch pot the dail says my vacuum is 100%
I leace the pump running over night.  In the morning when the resin is hardned the vacuum line form the ez composite starter kit to the pot is flat from the vac. 

(I dont have an official cacuum pump.  I use a 35l/m fridge pump. Whitch seems to work fine.   I can add an extra pump if i need more cfm...)
If my vac is to strong.. i can make a bleedvalve to reduce vacuum.   

But idialy i would love to have a perfect finish.

I use easy lease release agent..  denoulding is a breeze..

Glass and carbon are really a mismatch, the strength of fibreglass comes from its higher elongation to break and the strength of carbon comes from its high rigidity. If you combine the two, then the fibreglass carries all the load as the carbon will break first, which means you aren't taking advantage of the material properties of either fibre. 

But yes, you can get pre-preg glass. Likely not going to be something you can get in small quantities though.

Easy Composites have virtually all the information you need in their X-Preg processing guide and YouTube tutorials. If you're new to OOA prepregs I would start there, it will really flatten the learning curve.
