The quality of the charge pipes under the paint is very poor, You will struggle to get all the scratches out.
I've found wire wool and autosol works really well on the charge pipes but don't use it on the manifold
You do need a pressure washer to use a snow foam lance, most pressure washer have different lance fitting too so buy your pressure washer before buying the foam lance.
During the winter if the cars really dirty I use it for every wash, in the summer I only use it if it's got really dirty.
I'm quite pleased with my effort to be honest, can't help some scratches in it, and from a distance it looks really good! Took bloody ages though! I skipped 2k aswell as I only had 1500 and 2500.
