Getting started will set you back 2-3 hundred bucks american. But the tough part is scaling down the spray gun for small stuff like lures. The ongoing cost isn't too bad , comes out to about a dollar a lure, if nothing goes wrong. Let's face it if I was trying to save money on lures I sure as heck would not spend hours and hours making them...
As far as the silver fading; it really doesn't. It just has to be protected with the right clear coat. It can yellow though...to prevent that you just add a tiny amount of violet tint to the clear. I've been experimenting for a few years now and when it works ; you get an amazing looking lure. After all silver is the most reflective element on earth....
Its all about the satisfaction.....right?
By the way, I would love some feed back from fellow lure makers, I just started a YouTube channel https://www.youtube.com/channel/UCS9izgLp6k7siMTMU21ZoNw
(I don't sell anything or promote anything) It would be nice if you could tell me what you would like to see a video about.
