Chuckle, its so universal I bought a 6 gallon case of it, to be used to refill the quart cans when they ran low. It gets used for everything, although when time to clean off a PCB I've just repaired, I rather prefer acetone, it a better solvent for some of the resins in solder. >> FWIW, the painting business also requires quite pure, contaminate free >> solvents, purer then the stuff you buy by the 55 gallon drum to mix >> with nitromethane for your 1/4 mile monster. > >I'm going to presume that refers to a car. ;-) Dragsters, where the mileage translates to approximately 10 gallons per mile. :) Been there, done some of that too. >> The ACE Hdwe version comes in a handy container that can be carried to >> the job. > >I'm not sure what the abbreviation stands for, Hdwe is a common english abbreviation for Hardware. >but I've always hated >child-proof lids.

The Apollo tape sounds interesting! 1974 would probably have been a 3/4" sony u-matic. Quite common in the day, but that was early in that era too. No idea what the 1/2" format would have been, there were several false starts before u-matic took over the field for 20 years in the smaller markets. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
