surfacing agent

How much surfacing agent do I add to my UV lam resin so it will sand on the hotcoat?

Howzit rooster, Just shoot your hot coats with S.A. and use catalyst. It’s a crap shoot using the sun to kick them off, plus you need to double the amount of S.A. which in my opinion thins it out to much. kick it off with catalyst wait another 15 mins or so then put it in the sun to make it good and hard. Check the archives for the problems you might encounter by just using UV resin. Aloha,Kokua
