help with refurbing wheels

[IJY1984]

Evening all,

Noticed today that the grid wheels on my zt are showing signs of corrosion and I can see bubbling underneith the top layer

With my messing I have managed to take a layer off to which the under part is pretty black.

My plan is to restore them once the weather picks up but for the time being id like to sort out this mess temporarily.

Anyone know an alloy wheel paint close to the colour on mg oem wheels, any pointers on how to tidy it up would be appreciated

Many thanks
