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..

A good analogy I heard for it is it's kind of like having a piece of aluminium (your carbon) and trying to reinforce it with a rubber band (your fibreglass). If you take that structure and bend it, the rubber band will bend significantly further than the aluminium but it isn't doing anything to prevent the aluminium from bending. 


It totally makes sense!
But then, what is the purpose of carbon/Kevlar fabric?

Mostly damage tolerance
