Best place to buy paint aerosols?

[Pickled Piper]

Hi, I'm going to be fixing a couple of minor rust spots on a blue BMW.

Any recommendations on what to use for rust treatment and where to buy the spray cans for the top coats? I assume I will need a separate lacquers

Should I just go to BMW, Halfords, somewhere on the net?

Haven't done this for many years now.

Thanks is advance for any advice.
