I’d throw in enough UV powder for your lam. If this is your first time with glassing trying to lay up a 9’8 with MEKP it will be the fastest 30 min. of your life. Do yourself a favor and go with the UV additive. Take your time with the laps and make sure your have everything saturated. You should be able to handle the MEKP for the hotcoat.
order your gloss resin elsewhere and make it Reichold…you’ll get a better finish with it. (and i’m fairly certain that there is no hazmat charge for delivering only 1-qt of resin)
Quick question… whats the blank made out of?..better not be EPS if you are thinking of using poly. I’m probably sure you already though about it, but doesnt hurt to make sure.
What weight cloth and how many layers are you planning? That seems like an awful lot of resin to me but I’ve only done boards under 8’ so far. I have got away with less than a gallon of resin each to build mine and they are hollow wooden with the inside glassed aswell. A gallon is around 5 kilos so ten kilos plus gloss is well heavy even if you do sand loads.
