What does everybody else use for the wheel arches and underbody?

Btw, I don't have access to spraying equipment. I'll be putting Bilt Hamber Dynax UC or UB on top of whichever paint and underbody covering goes on.

If you're looking for 5 or 10 year protection, however, I'm sure any of the 3M rubberised undercoats or POR15 etc. will probably keep things looking decent for the foreseeable (without any real "maintenance").

Thanks for all your suggestions chaps.

There's surprisingly little rust on the underside of this car now all the bolt-on-able bits have been taken off the rear end (everything is off except the fuel tank). My plan for this year is to sort out the underbody all the way from the rear crash beam to the rear edge of the undertray. In spring next year I'll do from the front crash beam back to the rear of the undertray.

All of the rust spots I can find on the underbody are either where there's a spot weld, or where there's a bolt hole or a drainage/vent/access hole. I need to scrape away the factory coating around these spots and take the rust back to bare metal. (NB. None of the rust spots are serious - it's only surface rust on spot welds and around the rims of holes).

I already have 2 litres of Bonda Rust Primer and 1 litre of POR15 Rust Preventive paint. Either can be used straight onto bare metal or rust but they're red and black respectively so I'll end up with a bunch of red or black spots. The question is what to put on top of them to make it all uniform. I'd paint the whole thing black (with Manor Coatings Chassis Black) but I'm not sure how black wheel arches will look. At the moment the wheel arches are silver (body coloured) and the rest of the underside is a matt grey/silver/slightly pale brown colour - that's how it left the factory.
