I have my whole quad torn apart right now. The previous owner painted everything with it together. The head of every bolt,nut and washer has pretty thick paint on it. How can I get this off. I don't want to try to sand the paint off every bolt. I just want them to look back to factory with no paint. I painted a few of them and when I tightened them the paint scratched right off and they look like crap. What can I soak them in that will take the paint off with little to no extra work?
