hi, my vito has a lot of quit a lot of rust underneath. As far I can tell not structural, just surface rust. I have successfully treated and removed rust from the bodywork. But from what I understand to remove the rust from the underbody, you have to; clean, remove surface rust (wire brush it), clean, treat with protective layer.
But from my experience with body rust, if you don't get the last speck of rust out, and only paint on bare metal; a few months later the rust will peep throw again.
So how does this apply to the underbody, as you can only get the surface rust off and any protective layer would just sit on the rust. And presume keep rusting.
Is it worth treating the underbody? Bare in mind, I plan on keeping the van as its low mileage and previous owners spent a fortune on the vehicle.
And what is the best method?
