Rust underneath car but no advisories on MOT

Can neither of you get the spelling right! It's Bilt Hamber.

I can highly recommend their products. On those areas, if you want to arrest the rust (for piece of mind) you would wire brush most of the rust off and brush paint with Hydrate 80. If you want to protect any box sections (where rust might exist but not be visible) you need Dynax S50.

I live on the coast. 2 weeks holiday and the discs are covered in rust and I end up having to carefully brake for a mile or two to clear it

Bilt Hamber Atom Mac - dilute to 5% with water and spray on discs after parking up (esp if it's been raining or rain is imminent), maybe try slightly higher percentage for your problem.

Also, given your problem, Bilt Hamber Auto Wash shampoo, unlike most others, contains rust inhibitors. It's expensive, but you only need 5ml to a 10L bucket of water (I'm still using the same bottle bought 2 years ago). Auto Glym Bodywork Conditioner Shampoo also contains rust inhibitors (easier to find than BH).
