hmm, I can't remember where on this forum but I have seen a thread about this. The guy highly recommended using a scraper and NOT sanding it. This way you get a mirror like piano smooth shiny finish. I am sure it was a thread on a homemade speargun. Had a look around this is the thread with some useful advise from oneolddude ???
I am trying to copy the link but it won;t let me ????
under homemade spearguns thread is called customs spearguns pictures
it is a long thread !
