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..

Reinforcing carbon with glass is like reinforcing a steel wire with a bungee rope. Before the bungee rope is stretched enough to really produce any significant force, the steel wire will be already way past it's elongation maximum. The combination will still be just as stiff and strong as the steel rope, but with the additional weight of the bungee cord.
Either a glass or carbon sandwich might be the solution.
