Go for the two part poly. The difference in durability and gloss cannot be compared. One part poly paints are really not that much different from exterior house paint. More gloss on the marine one part but nothing compared to the durable shine from a blown on two part paint. I let this board convince me that I should pursue the two part blown-on process last spring. Good advice. Cost is the factor. I tried to rent space from an auto painter and decided that the best thing to do was to buy the lowest price quality that I could justify and bought the paint. There is really no comparison between the paint or the result. If you want a durable. glossy finish for your new toy fo for the two part. The result is a gel-coat strength ( almost) finish that will protect the epoxy and boat. Brian
