I'm working with TAP marine epoxy resin and various weights of mostly fiberglass cloth material. TAP is great but you have to find the experienced guy (like Home Depot or OSH) for good information.
I chose epoxy because it's odorless (CA neighbor friendly) and has good bonding strength. It requires more precise mixing ratios as I've found out the hard way.
The questions
Is the 914 top covered with a gelcoat? Does epoxy bond well to gelcoat?
How long should you wait between laying the next layer of cloth?
If more than 24 hours do you need to sand the surface for the next layer?
Is there a water soluable layer you need to wash off or you may have delamination later?
