I'm trying to find a good alternative to PBT/Durasurf etc for the topsheet of my boards because there doesn't seem to be any suppliers in Australia and postage makes the price to rich for my budget.
I've seen in a couple of posts people refering to 'pre-cured' and have seen the great results on the 'Porker' board a couple of years back. But, there doesn't seem to be any more info on how to do it and when you can and can't use it.
I'm guessing it means pre-cure a layer of light glass on a flat smooth surface and that put it into the layup as a finished product. But I've got a few questions that would be great to have answered before I commit resin to glass.
1) Does it just mean cure a light layer of glass on a shinny surface?
2) What weight glass is best?
3) Is it necessary to vacuum bag it to get a good finish and resin ratio?
4) Is it necessary or useful to put peel ply one one side to for better bonding in the lay-up?
5) what's the best way to avoid getting air bubble locked in the weave? I've tried a few different ways (elbow grease, roller) but still end up with a few too many?
6) how well will it conform to the curves on a board? Obviously it ain't going to bend around corners but will the curves you normally get from sanding a core so that its thins out smoothly towards the tips and the rails be too much for it to conform to?
Any other tips or suggetions greatfully appreciated.
Cheers
