Is there a reason you went with polyester resin as opposed to something like West Systems epoxy? I'm just learning about composites so I really don't know all the advantages. What grade of glass cloth did you go with, I'm guessing 3/4 oz? 1 layer? It seems like you'd need to sand the finished (even though I've heard not to) or else you'd get textured paint.
