I need to wire brush the chassis & sills on my P3 - and then paint them with a protective coating. And I'll probably treat them with with and anti-rust phosphoric acid product as well.
Have other members done this with their cars? I'm interested in what's the best method to get access and if there are any preferred products (I'm thinking about spraying on POR-15 chassis paint). I'm also thinking about jacking the car as high as I can on axle stands.
Any ideas/suggestions gratefully received

Thanks Neil
