Damn. Think of the $$$ you could make at a Antifa rally ceracoating the tip of every dude's willy bright red so that everyone knows his intentions and if he's invading a safe space. Billion$, I tell you. Billions!
What? Ceracoating needs to be baked on and their willies will fall off? You say that like it's a design flaw or something.
Perfectly legal - and I joke about doing it myself, to get around storage laws - I'd still be violating the law, but no one would know that the neon green Hi-Point with an orange tip isn't a toy (only choosing Hi-Point since they look, "Off" compared to other guns).
What is ILLEGAL is to paint the orange tip of a toy gun to look like a real gun. I remember as a kid, all the toy guns had orange things in the muzzle, which we all promptly removed - because who wants to look like they're carrying a toy? Can't believe what a felon I was at age 6.
