Swingarm touch-up paint ?

My RR was in at the dealer last week and they pointed out I had a small chip on the underside corner of the swingarm which had exposed the metal. It’s really small (5mm in diameter) but they suggested I get some paint to cover it up to avoid any corrosion.

Can anyone recommend what type of paint would be suitable for this ?

Thanks,
Stuart.

Whip it off and get it satin black powder coated and you will never have this problem again:)

Costs about £25-30
