Emron is a strong paint but has to be sprayed to get a decent finish and requires a posotive air respriator when doing so (versus a good mask). Emron is also getting hard to find due to it being dated. Most car restorers are using Deltron now, same principle, different chemistry. Check out John Casey's book "This Old Boat". Very good reading for this type of project with valuable easy to read information. For what it is worth, I found the two part polyurethane from Interlux was very easy to work with when brushing.
