ok, i can pick that up tomorrow. i wasnt sure it would be up to the task.
It will take off Remington's goofy epoxy finish from the 70's, it will take off anything.

I usually clean the item of grease. Then really glop it on thick, let sit ~10 minutes, but DON'T LET IT DRY, then in a bucket of warm water and a stiff brush scrub the loosened paint off. Let dry and examine. You may have to repeat application in spots. Just make sure to wear gloves and glasses. It is very nasty.
I've been testing out a mild caustic solution for the last few days, (I've avoided it like the plague upto just, but decided to stop being a *****), and it seems to be working well on paint and grease so far. Not heated, just water in a container with some caustic soda added. The body pieces of that little Baugh & Moss vice got dunked in there to shift the old paint which electrolysis wouldn't shift.
Slowly add lye (sodium hydroxide, not sure what they call it over there

) to a steel container of COLD water. Stir to dissolve, then bring to a slow boil and place in parts. If you've got the stones for this, next up is hot bluing.
****Just a note for anyone not familiar with hot caustics. This is extremely dangerous. Will burn holes through your skin. Never add caustic soda to hot water, always mix cold, THEN heat. Also note it will dissolve aluminum and other non ferrous metals, so don't go putting your aluminum xyz in there and wonder where it went.
