Pleased to report that with helpful advice from your tech team and some forum members I have now successfully made up 6 flat c/f panels in 195 gsm varying from rectangular 400 x 400 mm to triangular 2200 x 450mm by resin infusion. All have eventually come out without voids (yipee), there was some scrap. They only worked well once I heated the layup table to 22c, and heated the resin as it flowed with a hot air gun. I did use a lot more resin than in your tables, but the surplus came off in the peel ply. My panels are 0.35mm thick.

Now can you you help me with sticking these on my grp boat?  I have coarse sanded all the grp, 80 grit. I cannot control the temperature which is ambient in a big steel shed, currently 3c and 65% humididty. I therefore cannot use epoxy the glue them down, because any minor  uneven heating / cooling causes ripples, I have tried. The surface is compound curve, just, but I have formed the panels dry, by heating them till flexible and taping them down to cool. (It works!) I favour using pu 18 adhesive as it is flexible and waterproof, but how on earth do I get an even thicknes of such a thick sticky adhesive over such a big area??? and how do I keep the panels even on top of the adhesive?? Any advice and or clues would be greatly appreciated.

I don't know what your shapes around  the area   you are working on so ignore me if this is totally useless for your situation 

Thanks Bruce, yes i can mask around the part and put bagging film over, i can see that would also result in very even pressure all over. Good idea.. I am still concerned about applying the PU 18 though, anyone know how thick it is to apply? can i for example spread it out with an adhesive comb after applying lines of it from the gun? anyone used it? what do tech support think?
