Re: the 50/50 acetone & ATF mix...... you need to store it in a sealed can. A regular squirt can will allow the acetone to evaporate off, you'll need one with a threaded and o-ringed cap on the nozzle. And there's no need to buy expensive ATF, the absolute cheapest you can find (Ford branded would be good.
)
