any quick fix's for rusty wheel arch's??

WD40

Theres a paint called 'black magic' I think it's called, that would give you a good finish but I'm sure there are other ppl who may be able to offer better and cheaper solution.

if your good with your hands ,rub the paint and rust down,wait until its dry if not allready,get some metal primer and wait until dry and then get hammerite black spray paint or whatever the colour is,
would take a day probably if you did it right

Use Coca-cola - seriously, it works a treat!

How to do it

Depends on how rusty, how pretty you want it to look after, and how much time and money you want to spend. If you don't mind so much about the appearance I would do as follows. Place bin liner over wheel to protect from paint and metal filings. Get a nice stiff wire brush and remove loose bits and traces of rust. You're aiming for shiny metal. Very careful use of an angle grinder/dremel tool may also help get this done. Give the area a brush down to remove loose bits and give a quick clean up with some meths. If this left a hole you want to fill it in with some body filler, or if lazy/not too concerned on appearance primer bare metal then slap aluminium foil tape across it in layers. Get some primer over the area. I would recommend using acid etch primer, but tbh any cheap primer will be okay. You can then either slap on hammerite in a similar colour to your car (or black if there is not one, it doesn't look too bad if you do the whole wheel arch and use masking tape to keep a straight line over it.) Or you can get paint mixed up and give it a spray, with lacquer after if it is metallic/pearlescent. Red colours tend to fade on car so paint mixed to the original colour does not match.

If it is rusting on the wheel arches consider whether it may be rusty in load bearing areas that need welding for the MOT and will cost a lot to do. Often this type of rust is hidden beneath the painted underseal and does not appear rusty until you can poke holes through and peel the underseal off. This is why the MOT man hits the car in various areas to check for rust.

thanks for all your advice guys, i dont think the rust is anything serious as it just passed an mot last month, and only cost me £20, hench the reason i want to keep it (its looking after me)
i propably would be better off doing the job properly, but, i havent got the money at the minute, would it work if i just sanded it down with sand paper until it was smooth and then painted on top??

Yeah do that and slap some hammerite on. It's better than nothing and more than most people do. Bear in mind a sharp edge = mot fail if you come to sorting it and make holes in the metal though, but some body filler would sort that.

i dont think it would make holes in the metal as it just seems to be cosmetic, the paint has flaked away over 2 wheel arches and the paint is now bubbling, so, its ready to chip off! im sure ill do a bodge it tomorrow
