Resin and top coat will not adhere to the premade corner unless you sand it down and wash off any contaminants with asetone

Absolutely correct.
Cowboys that installed that roof dry fitted all trims by duct tape at the joints and then also failed to spread mating over them. Duct tape only had a bit of top coat over. Keeps me busy 😉

Another Fibre gkass roof bites the dust. When will people learn.
