Yeah....buy another gallon! This stuff stinks so pour in a well ventilated area. what are you using for color? For good color separation try to be patient waiting for the resin to gel. Don't walk away once you add catalyst (I am doing 3-4 drops per oz. resin) bc it gel before you realize it. I like to give my cups a gentle stir every 5mins or less. Be gentle so you won't add air back into the resin. Most importantly, have fun and experiment with colors and whatever else you can think of. Love to see how your first one comes out. Be sure to post some pics! Best of luck!
Be careful on the load . You will want enough to make the blanks as opaque as possible but too much will affect the curing . Also watch the reds , they seem to inhibit curing .
