For what it's worth, Venus
I would just keep looking until you find one willing to do what you need. You may have to search out a place that specifically does powder-coating, body shops that I service do not. During the slow periods, many of the smaller shops are willing to paint appliances with what we call single stage paint. The other paint is called base-clear and is used primarily for cars. Since I don't know how familiar you all are with automotive paints, I don't mean to talk down to anyone about it, but I don't always know how much we all know about different topics. I'm not familiar with powder-coating although I know what it is. Venus, I would just keep trying, just like you would in finding a certain appliance. One word of advice: stay away from these high production collision centers, their work is just fine, but they would probably be the least willing to help with a non-automotive job. They have little slow time and most of their jobs are insurance jobs, which keeps the business rolling. Good luck to you, and if I can find anything out, I'll pass it on to you and Austin-David
