I am rehabbing a 2005 Weber Performer. The lid was in rough shape with rust arond the handles and a few area's around the lip and some dings on the lid. First thing I did was clean the surface with some Dawn dish soap and 0000 steel wool. Then i hit the rusted area's with a really fine grit sanding sponge (I believe it was 800 grit but can't remember off hand) After that I rewashed it to remove any dust/rust particles that might of remained in the area. Then I put down some high temp spray paint around the rusted areas. I overlapped the surrounding area and then hit the surrounding area with the sanding sponge against to remove the excess spray paint. This ensures that all of the rust spots were completely covered by the high temp paint.
