Ok, great, thanks - good to know it's not tricky.
Now I've looked around and most of the stuff I've seen is the dual syringe type epoxy kits with the special mixing nozzles. Do you generally have to use those nozzles or is there another easy means of mixing precise amounts in tiny quantities?
The reason I ask is that those nozzles don't look cheap unless of course you're doing tons of the domes in one go, making a single use nozzle less of a waste. Is that just what people tend to do, ie make big batches of them in one go rather than one or two here and there?
It wouldn't matter with polyester resin as any volume of catalyst will cure the resin, it just affects the time, and heat, but with epoxy the volumes must be accurate or it'll not set right, so am not sure of another means of being precise besides those twizzly nozzles.
