rust spots

hi all,

on the way in to work this morning i noticed i have got a few very small rust spots on the tank, about the size of a pin head.

can anyone advise the best way to deal with them? obviously don’t want them to grow… bike is a Kawasaki z750 in silver.

i’m due an MOT and new brake pads next month, is it worth waiting and asking my man at the garage to deal with it?

many thanks
