Ed,

Thanks for your quick reply. I initialy planned to use West System 105 + 206 hardener which gives (from their website) about 25-30 minutes pot life. I don't know if it is enough, I planned to mix small quantities at a time but I don't know what happens at the join when the resin starts to cure, does the resin still soak in the cloth even when the cloth gets hard ?

Which brand of resin do you use ?

Is the brand of the glass cloth important ? I found a site (CST) who sells 2y of 0.7oz for 5$ or 10y for 20$, this sounds reasonable.

Thanks again.
