Wayomic - I actually got a bit more creative with my spraying. Instead of covering everything to protect from overspray, I took a box and poked a hole in it at the level of my arrow when on the lathe. Taped off the arrow where I wanted the dip to be and ran it into the box. Sprayed the shaft in the box with just some of the taped part of the arrow poking thru the hole.
Perfect with no overspray on anything - other then the inside of the box.
Using enamels though cause I couldn't find the flourescent color I wanted, rustoleum had it near perfect match. 1 Coat flat white then Flo Green. Going to tryTestors for crest paints. Those are enamels too, the only lacquersI seem to find are spray or limited in color selection. I will likely coat with an acrylic lacquer to protect and for adhesive reasons.
But I figure it's gonna be some trial and error before its all done
