i got rust starting to form on my left rear fender, but its really really small and not even noticeable unless you look really really close, and small little bubbles too. Do you guys have any tips or advice so that rust wont spread and shops that repair rust in case mine gets worst. Also, i dont know what it is called but its like a spray that prevents rust? like you spray it on your whole car... not sure  :lol: then it won't rust again

    After it starts rusting you can't do a whole bunch besides cutting it out. There are rust converters but they don't work well for the type of rust on cars.

        Nope, detailing just corrects defects in the paint. If it's just surface rust you could get them to sand/grind it out and then paint it, but there's a good chance it will return.

          Your best bet is to either replace the panel or have it cut out, welded, and re-painted.  It isn't always cheap to fix rust, but it is possible.

              Even if you cut it and weld in new metal you might have rust come back if it's daily driven in rain and snow. Depending on the severity of the rust you could be looking at $1000-$1500 a side at a good shop. If the paint is bubbling it often means the rust is coming from the opposite side. If you are going to repair it then I would advise getting some rust proofing done to prevent it from coming back. Unfortunately rust is inevitable.

                Being a mazda owner, i can tell you rust is impossible to avoid.  Once its starts, it doesnt go away easily.

                  yea, planning to use it as my winter beater then sell it after i have enough money to import a car. Can you tell me more about this rust proofing? and is it worth it? im guessing it would cost like 2000$ or more lol

                    if you are planning on getting rid of the car in a short time then I wouldn't waste your money trying to fix the rust. If you really want to get rid of it just sand it down, use a rust inhibitor like rustcheck or por15 and paint the spot just to cover it up. It's a quick and cheap fix but the rust will be back in 2-3 years. If you do the prep work yourself you can take it to a place like maaco and they will paint both quarters for about $300. The quality is eh but it's better than seeing rust in most cases.

                    Rustproofing is done to cars to prevent rust from occuring but it will most likely happen regardless. For rust proofing to be applied the area will have to be free of rust otherwise it won't work. There are three major rustproofing options; electronic module, tar like spray/undercoating, and an oil based spray. Not sure how well the electronic one works but it's supposed to change the charge of the metal and make it rust resistant.  The tar based one is essentially just a goopy tar they spray to the underside of your car or in wheel wells. It's dirty and messy but it stops water and salt from penetrating it. Oil based sprays get sprayed into different areas of the car (doors, fenders, etc.) and the oil prevents water and salt from getting to exposed metal. Price can range from $100-$1000+ and results may vary.

                      Thanks for the detailed answer! I might try rust proofing the car that im going to import since they're more prone to rust. Guess i'll just sand it down for now... Or till wait next summer lol

                        Another way to avoid rust is to not winter drive it, if you can afford / put up with having a second mode of transportaiton.
