Question Painting aluminum capping on exterior windows

The capping around my windows is dirty and stained with tape marks (probably from hanging xmas lights by the prior owner).

I want to paint the capping and need to know what kind of paint to use. I was going to use Rustolem.

Also, should I sand the capping and apply a primer prior to painting.

The capping is white, which is the color I want to keep.

Welcome to the forums!

I'd try cleaning it first! Mineral spirits [paint thinner] might help to remove the tape adhesive. There are also some cleaners that might help - maybe goo gone or even oops or goof off.

When you say rustoleum - are you referring to the spray cans or the quarts/gallons?
A rattle can might be ok since it applies a thi n coat but if you intend to brush it on, you would be better off with a quality latex paint. Latex will flex some as the metal expands/contracts with temp changes. Oil base won't flex and can peel if the metal contracts and expands.
