Does anyone know if matterhorn white or something very similar is
available in an aerosol spray can? Maybe Krylon or Rustoleum has a
similar color?

If you look hard enough, you will find the paint store that all your
local car dealers use. Once you've found them, it's an easy task to
take them a sample of the paint (or, if you know them, the paint
numbers -- every color has an assigned series of numbers) and have
them make you up a little spray can of it.

Here in Iowa City that'll cost about twelve bucks.
