If there is a down side to vacuum bagging, it is that you have no idea how well it has gone until it is too late to do anything about it. Fortunately, all is well, the biaxial cloth drapes very well and there is no sign of bridging or dry spots. The first photo shows the peel ply being pulled off, revealing a lightly textured surface. Any epoxy by-product is on the outside of the peel ply so there is no need to wash or abrade the surface before applying an epoxy float coat to seal the fabric weave. The second photo shows the surface after float coating. This will be washed in water to remove by-product, then wet and dry sanded ready for finish painting. I have read that peel ply is a useful tool even if you cannot vacuum bag. The tough surface of the ply allows vigorous pressure with a paddle roller without fear of disturbing the laminate below. It removes excess resin giving better fibre consolidation with less resin weight. There is also no by-product or sanding needed before bonding or coating. Colin [/img] [/img] Attachments:
