Re: Convert 14' runabout into fishing boat for the SW FL flats
Most people go with poly because almost all boat construction (especially early glass boats) were poly. So, for cost reasons and basic compatibility, most folks go with poly.
Its totally a matter of personal choice and budget -- as epoxy will work just fine. However, once you go with epoxy, you have to stay with it (because poly doesn't bond well to epoxy)... So, I think that does eliminate gel coat (poly based) from your finishing choices...
Also, you may want to use 2-part pour-in foam because the foam in many glass boats plays a "structural" role as opposed to simply a flotation role. We tin-boat owners can get away with blue/pink sheets, noodles, etc.., but most glass boat guys opt for the structural properties of pour-in.
All that being said, I tend to prefer epoxy myself. Everyone cites the added expense, but I found that the expense is mitigated by 2 things: Epoxy doesn't have "haz mat" shipping fees associated with it; epoxy goes a very long way (granted, I didn't use cloth, but I sealed alll of the boards on my 17 foot tinny (multiple coats) with only 2 gallons of epoxy vs. 15-20 gallons+ of poly on most glass/poly builds). Also, while safety precautions are still warranted (as some folks have skin reactions to epoxy, and its not advisable to breath it in, I found it to be a lot more "gentle" product to work with)... It doesn't stink, etc... (and its very strong)...
