  • I dont think its very damp... maybe I just cleaned badly and left moisture on it?

  • My bike rusts in my flat (it's that fucking damp in here). Clean and lube. Sorted.

    You didn't blow dry? Then there's your problem.

  • what's a good commercial rust remover? will it affect the paintwork around?

    hammerite kurust and no

  • ^ Jenolite is better IMO, used it on my classic cars.

  • The rust on the right leg of the fork looks quite advanced.
    This curve of the fork absorbs quite a lot of vibration and bears high load. This is the only portion that really concerns me.
    It may be feasible to take to her with paint stripper first; followed by a 24hr soak in muratic acid.
    You should only have peace of mind once you behold a completely silver and bright frame. A small brown blotch or two is not a disaster either, but should be treated further with for example: Jenolite
    If the rust does not get removed, and you feel like you are pursuing the rust deeper into the metal, then: dispose of her.

  • I have a newly acquired casati frame that has some surface rust:

    • on the chromed lugs
    • where there are small paint chips
    • on the chromed forks

    There is also seems to be a little rust when I look in the seat post and head post. grrrr

    My problem is that I love the paint job, a marbled purple, which is quite unique. Should I follow the route of using the jelly rust remover and grease spray inside? And should I do the bath/strip thing mentioned above? Where could I have this done?

    Thanks

  • If you do the bath/strip thing it'll need repainting.

    For removing the rust on the chrome, rub it gently with very very fine wire wool (or scrunched-up tinfoil) and apply a car wax to help prevent it rusting again (like Turtle Wax). For the paint chips, I would avoid using Jenolite or another rust remover as it tends to drip and this will damage the paint. I would very carefully sand off as much rust as you can, apply an anti-rust primer (like red oxide - spray a little into the lid and apply with a little brush), then normal primer, then topcoat - car shops sell paint touch-up bottles with tiny little brushes that are perfect for doing this, but it might be hard to find a good match.

    If the paint is metallic it'll need a clear lacquer over the touch-up, too.

  • Any opinions on the rust on this bike.

    may repaint or find some way of treating it.

  • most of it looks pretty light. the forks look like they could have a bit more serious stuff underneath.
    the drop outs look like they have snapped and been re welded

    i would say the best thing to do would be to get it stripped back, treated and then re painted. you will lose the current detailing though

  • @ lae

    Thanks for the advice. Will get to it ASAP.

  • wait! wire wool will damage chrome you need brass wool

  • how do the rust removers work ...
    DO they actually remove the rust or is there some kind of chemical reaction that converts the iron oxide into something else?

  • Do you guys know of any powdercoaters ? in manchester or nearby .

  • Is this common to a 27years old frame?
    Do i need to repaint the whole thing or repaint the affected area?
    Thanks.

  • ^Turn the bike back over and ride it.
    [perhaps a dot of grease on the blemish to keep out the winter salt]

    tell me thats some kind of sticker on the bb right? not a farking great crack?

  • Yeah its a sticker.
    There is some kind of bubble between the downtube and bb joint.
    Do i need to do sone scrubbing to id the rust?

  • Tricky one, you can try the "knocking" trick, if there's an area that sounds "dull" and the rest doesn't there's definitely a problem.

    I'm anal and would sand it down, then Kurust it and then put Vaseline or Waxyol on top to keep the damp out. If really anal do a peek inside but that would remove the BB.

    Nail polish and Humbrol may give you a good paint match.

    Opinions on this? I quite like it...but it's in Japan so a major hassle and the rust does look...not so good. Well it's been on e-bay for months...
