I totally appreciate this looks messy and archaic. It is! While I'm building these molds so they would be stout enough for reuse, they are still done with less attention to detail than normal as the final parts will be covered with leather so hyper clean molds is trumped here by get'n it done. Parts will be stout and clean.
More pics of the molding process. More flanges and gelcoat below. For sure brushing gelcoat, instead of spraying, is less than ideal. Again, still good just not the exact proper process.
