I bought a large plating system a few years ago and just recently got it up and running. doing zinc base coat with chromium top coats (yellow black and blue/clear) i am lucky as i have all the tools in the toy box to clean and prep but its still a ton of work and very time consuming. I thought about it to add to my business but its just too much work for the return. talking to a bike guy locally he just paid $8 per bolt that he had refinished so i think the resto world vs the industrial world has very different pricing (and quality?) i am still learning so wont give up on it yet.
