re: WD40 and paste wax

I was "forced" to use WD40 to get the gunk off the surface (that was the suggested method from Cutech).  I wiped that off as much as possible.  I've run a few boards through, and then wanted to add some rust protection.  My go-to has been Johnson's paste wax (yes, I still have some!!).  That has worked fine, but concerned on what impact the prior WD40 would have on the subsequent application of wax.  

And I already somehow had contact between a cutter and the guard 🥺.  Didn't seem to do much beyond marring the paint on the guard.
