I opened my first can of etch prime and it was very thick. It is to be reduced 1:1 (SWilliams product E980)I mixed it with a paint stick but that took a long time. I'm thinking I should use, maybe my wife's eggbeater or electric mixer. Is that a good idea? How about one of those mixers that chuck into your electric drill? How do the pros mix their product before emptying it into the spray gun cup.I can't afford a shaker.
