paint scratched steel frame
hi all,
Looking for some advice. A friend is trying to offload a good quality steel-framed road bike to me, the only problem is that the steel frame has been scratched and lost some paint, quite large areas around the chain stays and forks. Now, my question is - is it really bad to not get a respray? I live in a relatively wet area (scotland!) and I want to cycle through the winter, so no doubt the bike will get quite wet. How quickly will the frame rust in the rain? Any advice? Thanks! Tom |

How quickly will the frame rust in the rain? Any advice? Depends what it is made of. If it is a good quality frame then it will be an alloy steel that is a bit more resistant to rust than cheap hi-ten steel. Depending on how bad the paintwork is, it should be possible to give it a rub down on the worn bits and paint it with whatever is to hand. Alternatively a shotblast and powder coat will cost about 40 quid. If it has manufacturers lables on it indicating the grade of steel used, photograph them and note the manufacturer and frame number. You may need this to get replacements after a respray. ...d |

Alternatively a shotblast and powder coat will cost about 40 quid. Any idea of people who would do it that cheap? I might be tempted at that price. The only problem for me is I guess it requires deconstructing the cycle (ie removal of all the components), which I'd have to pay someone to do! Tom |

Modern shotblasting uses plastic beads becasue they are nicer, except when steel is used for peening the surface in certain treatments. Where are you Tom? then reccomendations can be made for painters. Alternatively just splash some car touch up paint on the worst bits and ride off into the sunset. It won't be as good but it'll look less nickable and provide reasonable protection against rust if done well. 501 won't rust terribly quickly anyway so you should be all right for a few years. ...d |

Where are you Tom? then reccomendations can be made for painters. I'm in either Bristol or Edinburgh - the bike will initially be in Bristol, then it will move to Edinburgh next month!

Thanks for the advice David! Edinburgh is about as damp as Bristol, if not a little drier. There are several powder coating places in Dalkieth which is pretty close to Edinburgh. Though my first option depending on condition would be to take off the appropriate parts, clean well, sand with emery paper or similar on the metal bits anbd use a car touch up kit to tidy up the bits that really need doing. Alternatively just leave it, or use something like hammerite in small doses. ...d |

A respray is not expensive. But there is rust and there is rust. A 501 frame will generate a surface layer of rust but this will take some time and will be easy to deal with. The frame is also likely to be plain gauge tube of 1 or 1.2mm wall thickness, so plenty of material there to go. The point to start worrying about needing to do something rather than just wanting to is when the rust starts to flake off. Compared to the steel used to make car bodies, 501 and better are very rustproof (though not as good as stainless steel, but that has other properties that are not necessarily so desirable.) Which reminds me, I really should do something about my commuter frame at some point. That is in need of some TLC, and possibly a new pair of forks. ...d |

If it were 531c, there is very little metal there, and it doesn't take much visible rust around the bottom bracket of a 531 frame to be serious. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ ;; when in the ****, the wise man plants courgettes |
