I actually did that after gluing it down , two minds alike !
When squeegeeing the glass over the top the cork was sucking the resin up like a sponge . It is amazing how porous cork is even though it looks relatively solid . I think the cork itself sucks up resin .
When i did tests before diving in i was amazed how tough resin soaked cork is . ( impact tough not tensile strong ) .
Bagging wetted glass over the cork would be soo much lighter , but i suppose you would loose the solid ( and heavy ) as a rock sandwich material .
I still think bagging cork would be perfect . Mabee next time ?

If the cork sucks resin then if you had bagged glass on it may act as a bleeder type material and suck to much resin out of the glass, justca thought.
So you sealed your cork with epoxy let it dry and it still sucked resin?

I think you should have a look on swaylocks forum guys were doing lots with balsa as a sandwich maybe they might have cork sealing ideas. I know they seal their EPS foam before glassing.

The technique i used was because i wanted to see the cork .
If i was just using the cork as a sandwich medium i would have used a squeegee and coated it with a resin Q cell paste mix . It would have filled the voids and stopped the resin seeping in . Just doing this all things the same i think i would have saved 1kg . Also i had to use straight resin for the filler coat . It would have been lighter and easier to sand if again i used Qcell .
I would estimate still using my primitive lay up method using Qcell in many stages ( including resining the top cork down ) , i may have saved up to 2kg.
Beauty has a cost

The board had its first outing today. 15 kts , 9.4 two cam . Totally rapped , I could not be happier. Blending three boards worked great. I know that it's going to sound like a new board advert , but it does go faster , smoother in the chop , turns better and planes just as easily as my favourite Xcite ride. It is however considerately more wobbly to uphaul but doable when the wind drops. I didn't at all notice the weight so I could only imagine how much better a lighter bagged version would feel. Shape wise I wouldn't change a thing.
Cant wait to use a less whopper of a sail.

Great job Imax.... Beautiful finish.

I will have to be careful with the resin on mine... Think Ill use microballoon/resin mix to seal it off.

Did you wet the glass on the board or did you squeegee it on a table first?
