Rusted surfaces- what to do?
If you have surface rust in the area you want to paint, you should remove it first if possible. There is a product called Rust Avenger that comes in a pen-shaped container. Similar products probably exist. It can likely be found at Wal-Mart and many auto parts stores. When applied, it converts the rust to a black, paintable surface. Press the tip, allowing the liquid to fill the tip. Touch the tip to the chips and the solution goes to work. It only takes a few minutes to use, unless of course you have hundreds of chips to address. Another product that can be used on larger chips or more severe rust is a sanding pen made by 3M. It appears to have a fiberglass tip that is used to rub away rust in medium to larger areas. The tip is about 1/8 of an inch wide but we suggest using it in areas 1/4 inch or more. If you use this, be careful not to scrape into the adjacent paint finish.
