    Following my previous thread about the bonnet heat shield, I had a closer look at the bonnet and noticed some 6-8 stone chips that started rusting.. so the paint around them looks like it has rust underneath.

    Now the spors are very small, probably the largest being ~2mm diameter and I am aware this is a 13 year old car so no longer new.. but what's the best I can do to prevent the rust from developing any further??

    I have some 20-30ml paint done after my colour code and it's spot on, could I fix this myself?

    Thanks, given the fact that I've never done this, what are the chances I mess up? :confused:

    Don’t dremel it... just touch it up, it’ll most likely be fine.

    If you want to stop the rust, you will need to get rid of the rust, which means back to bare metal.

    I'm with OptimusPrime here and that exact method. I used to be a corrosion engineer for Rolls-Royce (engineering, not cars) for a decade, and painting over is no fix.

    I've seen that AmmoNYC vid before and it's pretty good. Without watching it again, I think he also makes a good recommendation of getting a bottle of touch up paint, and diluting with a quantity of lacquer to get a better finish. It's all time though, and a good polished afterwards is a cost if you don't have one.

    If you don't fancy doing it yourself, get some quotes for that plus a bonnet respray. Or you could dremel, treat fill and lightly wet and dry yourself to save a bit of labour before a respray.
