Ive dropped around 3-4 grand on everything so far. still dont have everything I need. I mean u got 400 dollars in containers 4-500 dollars in dye. Then u got a couple hundred in chemicals/acids ect. For a 2 gal setup your looking at to set it up right around 1500.
2 Gal sucks the tank size is impossible to fit a whole gun in at once so your left doing a couple pieces at a time. A lot of veriables factor into if your colors match such as if your anodizing bath is a different temperature. The Color blue you get at 68 degrees acid vrs 75 degrees acid could be several shades different.
Im using a 20 Gal system now I can fit several guns in my tank now it works much better for matching colors.
