Rust spots

After cleaning my car today, I noticed a couple of little rust bubbles. What is the best way to deal with these? I can remember on my first car I sanded it down, primed and sprayed (that's how I'd do a door on my house!), but it was a £100 car and I didn't really care if it went wrong. Just wondered how everyone else does it?

We take ours to a bodyshop mate

Bit more expensive but at least you know it is done right

If you know how to do it, why not try and if it goes wrong...THEN take it to a shop

Maybe I'll have a go at one patch, but I'll check how much all the bits will cost - it could be more than it's worth.

I recently fixed three rust spots on my 325; two were underneath fender wells (not visable) and one was dead center at the top of my windshield.

After getting a quote of over $600 PER SPOT to fix the three problems, I decided to tackle them myself first. I figured I could always pay the bucks to a body shop if my work was substandard.

The spot on top of the car ... I pulled away the gasket at the top of the windshield, used a Dremel tool (on low speed) and a fine sanding disc to remove every bit of rust - down to bare metal. I then applied three coats of primer (waiting the desired time between each one before applying the next coat), three coats of BMW paint, and four coats of clear coat, again waiting the desired time between each one. This process took about three hours total. Then I used rubbing compound a number of times to bring up the finish.

The only thing you can even see is a small dimple where the original paint was (as if I didn't put enough layers on it), but this dimple is ONLY noticable if you're looking hard for it.

It's been over three months now of rain and sun, and the spot looks as good as the day I did it.

I just spent all weekend sorting out some rustspots on my car..the arches were going abit and i had a bad stone chip about the size of a penny by the rear window..i'll post pics when its finally done..it still needs some cuttin in etc at present

It sounds like I should have a go - more stuff for the shopping list!
