The panels from RD have some sort of primer coat on them, I don't think it is a weld-through type. Just wondering what the typical prep process is... Where I need to weld, I've been wheeling the coat off and applying weld-through primer. For the rest of it, it looks like everyone applies an anti-rust coat- are you removing the existing coat and using your own primer, then applying anti-rust, or just primering and anti-rust right over what's there?
Thanks... |

It's not a coating, it's galvaneal so it's right through the metal, but I'd hit the welding edge with a wire brush or scotchbrite pad and degrease it.
Don't use brake cleaner it becomes a poison if you burn it. They then spray it with a weld through primer, as it can rust along the weld seam. A few of RD parts are painted (mostly brown primer IIRC) those of course you have to sand back the paint. Like all welding make sure you do it in a well ventilated area. |
