I have never used a hydrodipper but I know there are several in the valley that do motorcycle parts, tanks, helmets etc. so I would assume they would also do guns and bows. Check out Phoenix Hydrographics or Spookyfast customs. Like I said, I've never used either so I can't speak to their quality. I will say that spookyfast builds some amazing bikes and everything I've seen from their shop motorcycle related is top notch. Hope that helps
