greg- have you ever tried a 2.5 oz. ‘veil’ cloth? my thinking on this is spurred from a recent post about fiber/resin - if we used say 4 or 5 layers of this type of cloth in conjunction with resin(poly or epoxy), do you believe it would make that big of a diff in compression strength? when we make tow boards, there are 3-4 layers of 6oz on deck and 3 layers on bottom. yeah, those boards are heavy, but what i’m after is the same effect of many layers of cloth- only utilized with epoxy. you have stated that you can lam one of your epoxy boards with more cloth than a normal poly board. and since the 2.5 would hold less resin, in theory, more layers could be utilized. any thoughts?
Generally using more layers of a lighter cloth does give you a better fiber to resin ratio. I have used 2 oz. and the finish is quite nice which means less resin in the hot coat as well. Some of the guys I sell to use 3 layers of 4 bottom and 4 layers of 4 deck as their standard lay up and they get quite good results. I don’t generally use that much glass but I have built some that way. When you do the boards are quite water tight as well.
thanx for your input greg- always appreciated, chris.
