Clear finish over Bote Cote
After too many years of part-time restoration and full-time procrastination I have finally started the final painting stages for my hard chine plywood runabout. I plan to have some areas of clear finish (at least initially) such as the foredeck, transom and gunwales and accordingly I have prepared these areas with two coats of Bote-Cote NY epoxy.
The "Boatbuilding with Bote-Cote" booklet I have recommends for clear finishes that "to maximise the coating life, apply three coats of clear, UV stabilised polyurethane over the Bote-Cote".
Can anybody recommend a suitable single pack clear polyurethane ?
Thanks

Three coats of whatever clear you elect to use, should be considered the bare minimum. I live in an environment, much like yours, with a high sun, lots of heat and many days annually of it. If you apply just 3 coats over anything here (and assuming there), after one year, it will need touch ups, otherwise the underlying wood will start to darken, burn and general breakdown from UV. The way I see it in my tropical climate, is a coat a year is sacrificed to UV and you need at least 3 for full protection. So after just one year, the top coat is eaten up and damage starts to occur.
My point, put on as many coats as you can. A top quality, show boat will have a lot of coats, say as many as 20, though 10 - 12 is common. These finishes are smoothed, buffed and polished, so some of the top coatings are ground down a bit, but this is the price you pay for these mirror finishes. Most can't do or want to live with this trouble (it really is trouble, trust me), so 6 coats offer a few years of protection and no risk of burned wood if you keep after any repairs (nicks, dings, scratches, etc.) as they occur. In a few years, you'll sand it lightly and put on a couple more coats, bulking up the film thickness (the real key to preserving clear coated wood), to protect against UV.

Thanks jmk89 - I had a look at Norglass products and they also have a Weatherfast Poly Clear Gloss which I will probably use.
Thanks also to PAR - I have seen your counsel before about the difficulty in establishing and maintaining larges areas of clear coatings - I suppose that is why they call it brightWORK ! The equation for me at the moment is does my desire for brightwork match the amount of work I am prepared to do for it and I guess it does. So if 6 coats are needed then so be it.

Yeah, you got it and it really is how much you can live with. You have to really want it if you have a good bit to maintain. Make as much as you dare bright, as you can always go back and paint it, once you've gotten tired of dealing with the maintenance of clear finishes.
