EXP,:
when I make a cowl)just an Idea I came up with? ,I spray PVA and let dry really well, then I do 2 layers of 20 min epoxy, the 2cd layer I put on 1/2 hr after the 1st layer gels up. then I use 1hr epoxy for the 3rd coat ,1/2 hr after the 2cd coat has gelled up and then I put on the 3rd coat and wet it all out. then I put on the cloth 2 layers back to back. then it's time to vacuum the cowl while the 1hr is still wet,I use low temperature release film,then breather bleader materal, on top of the cloth,Now the fun part, Seeing that my cowl is 4inch wide and 27 inch long I use a food saver bags and bagging machine to vacuum the cowls down. (works great)some places for infomation. www.fibreglast.com ,I use there stuff ,
