I've only done work with epoxy as a glue, but that guy does not have a good handle on what the hell he's doing.
Sorry; didn't mean to come across as cabin fever dissing. But the shape not all that pleasant and he should have tried for more of a boat tail instead of some barely rounded off foam. The t-shirt telegraphed the wrinkles in the tape; what the hell was he thinking? Then those brushes were a joke for that amount of epoxy. Oiy! I want to slap my forehead!
