Paint Removal

You just use as much water as you want paint remover. A gallon will be a good amount to begin with to sorta experiment with. Add corn starch to the water FIRST till the water is the color of whole milk. Then stir in the lye slowly till the mixture begins to thicken. Add just enough to make it the consistency of thick gravy. Paint in on with a brush.
Use safety glasses and gloves. It will sting if it is gotten on the skin but will not burn if rinsed off soon with lots of water. Vinagar will act as a neutralizer.

Let is sit on the tractor etc as long as possible without it drying out. Then wash off with the garden hose or a pressure washer if one is available. You can do it as many times as it takes to get it all cleaned off. It will not harm the wiring.
The secret of sucess is the thickening that the corn starch contributes to the mixture. This allows it to stay where it is put and not run off and dry out too fast. Water and lye would do the same thing if it would stay put but it won't.

We get our lye at the grocery store here but I have heard that it is also an ingredient in some illegal drug and lots of stores no longer carry it.
