im was going to try and make some parts as ive done few things with my dad for his boat with the stuff but i wanted to know if anyone has tryed this a failed? or if the parts are just never strong enough i was planning to use say old spolier for the 6 and use it as a template for a fibreglass mould would the part hold up?. i know depends on how thick you make it ect but just wondering incase im trying something others have and its just not worth it.
