Hi Im Sanjiv also 62 years old working on my Smit Rotterdam. Earlier builds have been 2 static models of Sultana and Mississippi then a small Rc Tug and now an RC Smit Rotterdam. Still pretty much a novice. Need some help. I started on fibreglassing the hull then wasn't very successful due to the many curves and bubbling and had to abandon the fiber glassing and did the Epoxy Resin only instead. I've sanded the resin and want to know if 1. its absolutely necessary to use fibreglass 2. can fibreglassing be done over epoxy and finally can I just do 2 more coats of epoxy resin and will that be enough. Any suggestions , directions will be really welcome.
