Yes, it is a chemical conversion

Epoxy resin is a 2 part adhesive, so there can be no sprays as a spray only contains one substance.
A modified epoxy resin contain substances added to improve the properties.
If it is plastic (many speedboats are metal) it will be the plastic Epoxy Resin (exactly the same as the glue) with fiberglass cloth to reinforce it. Epoxy Resin is very strong but somewhat brittle (like concrete), the fiberglass prevent cracks in the Epoxy Resin from growing and reinforces it (like the steel rebar in reinforced concrete does).
Yes, indeed. Epoxy resin cures by chemical reaction. Any chemical reaction is speeded up when you heat it, but when you cool it in the fridge, the reaction slows way down!

Epoxy resin is a nonmetal.
Polyurethane isn't epoxy, but they're both resins. They're also both reaction copolymers--you get either one through a chemical reaction between two components. The difference is, epoxy contains epoxide and polyamine; polyurethane contains a complex alcohol (either a "diol" or a "polyol") plus an isocyanate.
Specific heat capacity of epoxy resin depends on chemical structure of epoxy resin and range of temperature of measurements. Usually at 25 deg.C specific heat capacity of epoxy resins is 0.8-1.2 kJ/(kg*K). The specific capacity is growing with temperature, roughly increasing 1.5 times by 100 deg.C.
Epoxy resin can be used as a jointing compound.
Epoxy or polyepoxide is a thermosetting polymer formed from reaction of an epoxide "resin" with polyamine "hardener". Epoxy has a wide range of applications, including fiber-reinforced plastic materials and general purpose adhesives.
Epoxy resin can be used as a sealant on counter tops to help make them resistant to scratches. There are no countertops made of epoxy resin
Phenolic resin is less costly and easier to work with than epoxy. Many epoxy resin systems have a very short pot life.

Mass Epoxy Resin seems to be good value.
Fibreglass resin is a polyester.
