Yeah, A few years back, I did some of the white Crayon "Highlighting" on a
Glock 17 Slide. It came out nice.
That was a far as I was willing to go on my pistols.
A few monthes back, i decided to "highlight" a couple knight's panels, They came out nice and they remain
on the bottom 6 O' Clock of my RAS/RISs.
Again, that was as far as i was willing to go with my rifles.
The cool thing, is if you don't like the outcome, a little hot water and a tooth brush
will return your lettering to normal.
