Rust spots, how should I proceed?

[PLuKE]

Evening.

What will be the best way of treating this before I atempt anything myself?

I looked at buying Hammerite Kurust on the exposed rust and then using a touch up pen.

Leave the bulbling till the paint flakes off, and in the mean time coat with oil?

Thanks for you advice, looking at a DIY project, unless a bodyshop would do it for a reasonable price?



Thanks
