Think it depends... Not sure if you can weld the plastic, had my ED30 rear sprayed the other week and there was a crack near one of the corners looked like it was damaged taking off. Got round it by staples and rivets... Sanded down filled and then a fibre glass mesh over the back.... Couldn't see it after painting. Then took a few of the location lugs (or whatever they are called) out and it all went together nicely...
