Every LPI soldermask i know about uses resin and hardener.
There really is a type of epoxy 1 part only cured in UV or very hot
temperatures. The prices are about 45+ usd for 30ml, to 100+ usd for 1
gallon (or 15usd for 2oz as a surfboard glue). So the epoxy green
soldermask which originated the thread really seems a great deal.

I know the diference, but yes i ended mixing them in the line. Most
outdoors are printed in paper, and not with the ink i was writing about.

Yes! And sorry for my bad writing again. I should write less or use the
dictionary more often.
