I have a genuine df29 mono and have begun refinishing the old interior.Does anyone have any ideas on getting all of the old epoxy,shoe goo and dried up ca off the hull? I mean anything other than sanding etc....any tips of ideas? the ca I used to hold down the velcro battery strips has gone kinda gummy.And is epoxy or jb weld better than another for using on a motor mount as I have seen both but just used epoxy normally myself?
