I just did a search for repainting the hardware on the exterior (such as hinges, brackets, etc.) and didn't find anything specific just body prep. I want to repaint them and I'm just wondering what kind of prep work I need to do. I know a lot of members have done this, I'm just wondering if anyone can give me any tips. I understand I'm going to have to sand, but some specifics on grit would be greatly appreciated.
