I have used both NuFinish car wax and Johnson's paste floor wax and could see no difference.
I have also completely disassembled the Redding powder measures I use, both a BR-3 and a 30BR. Cleaned all the moving parts with acetone. Then wiped all machined surfaces with a paper towel with Kroil on it. Buffed it off so there was no residue on the surface. Basically filling the "pores" with Kroil. I could see no difference in operations of the powder measure between the Kroil or the two different waxes. And I've never had a corrosion issue on either powder measure.
I typically do the clean, rewax or reoil once a year.
Keeps them running smoothly.
