    Default fender rust

    Have fenders with OK chrome & no rust on the top, but lots of rust on the underside.
    Am looking to prevent it from rusting thru the metal and making it so you donít see the underside rust.


    What do you guys suggest?

    I too have A GS with the chrome fenders. There is a thread on here about this....one member soaked his fender in white vinegar to remove the rust, then sprayed the underside with a few coats of spray on truck bed liner. He said it worked well as a long term solution, so I did the same with both my fenders. I bought a few gallons of white vinegar( around $10 total) soaked for a couple days and the rust scrubbed right off with a wire brush...rinsed then dried with compressed air and sprayed on truck bed liner. The can of truck bed liner was less than $10, came out looking great. The member who originally posted about doing this said it held up great still after several years.

    The only problem with the bed liner is that water (Moisture) will get in behind it eventually and rust really bad before you know about it. It will work but that is a downfall to using it. Just think about all the stuff that gets picked up on your tires and thrown against your fender constantly.

    Por-15 paint would be good. Derust first of course.

    Scrape & brush the underside off pretty good and spray it with Rust Reformer from Wal-Fart. Works good, find it in the spray paint area.

    Get rid of the rust and pour some Hammerite waxoyl into the fender let it run under the re-enforcing bracket and the hard to get to places spread it all over using a brush sealing the edges when it goes off it lasts for ages

    I had mine off a week ago and just wired off the flakes and sprayed it with some outdoor furniture paint I had in a box of junk. It was green.
    I figured if it lasted 35 or more years this would take me to the rest of my life.

    I drilled out the mounting bracket from mine (it was rattly anyway) and scrubbed all the rust away before coating it with Hammerite. All good so far and the mount is now bolted up so easy to remove in the future.

    Thanks for the tips.


    I got some Metal Restore. Will give that a try.


    Had a broken sidecover that I replaced & had painted to match the other one.
    Iím thinking of have the shop paint the fender top surface to match & the underside with some rust inhibitor paint.
