RE: Safety warnings/concerns about 50/50 mix of tranny fluid and acetone. While I'm as safety concious as anyone I was amused at the extent of warnings from posters. I wouldn't envision someone mixing 55 gallon batches of the stuff then applying with back-pack sprayers. It's more likely that it would be mixed a few ounces at a time and applied in drops. In un-sticking a stuck 440 it would take several, maybe lots of drops but it's no worse than spraying or dripping on a like amount of any other penetrant. Now days it seems everything comes in areosol cans including penatrants. I tried the mix and it works very well and when the acetone combines with trans fluid it calms way down in volitility. It's the same acetone that we all use with body fillers, equipment clean-up and many other uses around the shop. Yes, always be careful using flamables. PK
