    You'd be best advised to download the free "user's guides", from WestSystem.com and the "Epoxy Book" from SystemThree.com. Procedures and the basics are well covered.

    Also, look up the series of 'how to' for Pygmy Kayaks fibreglassing on youtube. They have some great hints on techniques



    ps - the best technique is to apply a coat of epoxy first, let it cure, sand it then apply the fglass and epoxy.

    Rubbish.

    The best technique is to let your friends who've suffered through learning by doing (twice over) do it for you, while you go off to buy the beer, corn chips, salsa and chocolate....

    A couple bottles of red wine helps, too.

    Worked for me.

    I disagree. The best method is to apply a sealing coat of epoxy, let this go tack free, then apply the cloth. This insures a chemical bond, eliminates the needs to sand things, which often has you expose raw wood again, etc.

    Pars suggestion is totally correct but has traps for the inexperienced user. There is also not a problem with applying the cloth using the ' dry' method where the first coat is the one where the glass is laid. The strategy you adopt will depend on the size of the job and your circumstance. For example wetting out cloth and the tinber at the same time is a longer process and needs more organization for continual mixing as you go . The chance of de laminating the cloth from a n initual sealing coat is very low even if done days later. It also is a better approach for clear finish
