    Anybody got any advice on looking after a steel mtb frame. Had mine for a year and a half now and its starting to get some flecks of rust. The winter (and last summer 🙄 ) muddy conditions have worn the paint from the inside of the seat stays. Should I paint these myself with hammerite or just leave till it gets really bad and get it stipped and resprayed?

    It must be better than nothing though!?

    Does it just flake off orsomething?

    I tend to do nothing.

    Most tubing is so thick a bit of surface rust is not going to affect it for a long time.

    I’m guessing the DMR so I doubt it’ll ever rust through like my INbred which has had plenty of rust spots since 2002. It’ll probably fail at a weld or a tube snap/crack before the rust affects it (or rust through from the inside)

    But if you want to do it properly then it’s just like cars, rub the area down and touch it up. Hammerite will be fine. You might want a proper metal primer/undercoat though to make it stick properly.

    I’ve always fancied stripping a reasonably stout steel frame down and leaving it to rust :0)

    Nothing wrong with smooth Hammerite in my opinion.

    However when a similiar thing happened to one of my previous bikes I always tended to spray it with WD40 after cleaning and wipe it over, or in the Winter I would wipe the frame over with a light oil like 3-in-1 every so often.

    As Tom said, surface rust is just that, merely cosmetic and not something that will affect the tubing for a long time.

    Send it off for a professional respray. They shot-blast all the surface rust off and it should look as good as new when finished.

    Yes its the DMR so I guess I’ll just leave it and get it resprayed in a few of years or so. As for leaving a frame to rust; it may look good but picking it up would feel like nails down a blackboard!…. and you’d get covered in orange.

    hammerrite would flake very quickly…

    unless your priming it all, lackering it afterwoods etc, but still after that its not the same effect that’l be on your bike

    Paint only flakes if it isn’t applied correctly or if the surface hasn’t been prepared properly.

    I’ve used smoothrite spray on my pikes after rubbing them down with scothbrite pads, no flaking.

    Well I touched up an old rebuild I did years ago with Hammerite no problem.

    Luckily the blue was an excat match to the existing blue on the bike, had to touch up various frame locations and totally repaint the forks.

    Generous lashings of Nitromors, a stiff wire brush, some emery paper and Voila. A job well done.

    Bike was a very old 10 speed racer and used for work commute where it was left exposed to the elements for 10 hours a day with no problems developing to any of the paintwork that I had restored that could not have been attributed to just normal wear and tear.
