Planning on spending a few grand on a new SUP? Don't want to see it get chipped, grazed, blemished, deteriorate due to UV rays? Well wipe down your board with alcohol or metho and wipe on Evershield. Super strong, flexible ceramic clear coat.
It does say however for best results to cure at 120 F (48.8c) for 10-20 minutes. don't think I'd want to take the risk of delam, what is the temp for delamination anyway?
I would say that if it was being used on a plane or something super high performance then you might want to cure it for best results. Probably not really required for a SUP.
However, with that being said 15 minutes at 49 degrees would not delaminate a new board if the temperature was increased graduallly over a 45-60 minute period to allow enough time for air escape from the breather due to expansion and then a further 45-60minutes for cool down.
In Kununura i have paddled in 38 degree heat for 1hr or so, with the sun beating down on the board the whole time, no delamination on my HOBIE Race after 12 months. (admittedly I normally go out when it's around 34-35 degrees in the afternoon, but just for comparison sake) so I would not think an extra 10 degrees and exposure of just 15 minutes would cause any issues.
I wouldnt think you would pint it over your deck pad. :)
Also in reply to applying it to epoxy, it would not be an issue as the the top coat of moast board is like a clear top coat. With that being said I cant see there being any issue with caoting an epoxy board with it. It is not corrosive, it will just stick, dry and harden to an amazingly strong yet flexible shield. I might get some and paint one of my second hand boards.
