I have a Linus Roadster and it got scratched moving cross country. I love this bike and want to touch up the paint job. Has anyone had experience painting over scratches on bikes? Should I bother? Thanks!

You can buy touch-up paint for cars at an auto parts place, in a wide variety of colors. Often this comes in small vials with a brush in the lid, or even in "pens". At the same time, pick up some metal primer in a similar container, and be sure that any scratch down to the bare metal gets a touch of primer, even if you never apply the finish coat. –  Daniel R Hicks Jun 5 '13 at 19:23

I'd never heard of this bike - to save anyone having to look it up this is a steel frame –  PeteH Jun 5 '13 at 19:35
    
You can either do it yourself in several ways, or companies such as HotTubes can do custom paint and/or repair. –  JohnP Jun 5 '13 at 21:00
    
Scratches are fantastic for making people avoid your bike. –  Batman Apr 30 at 16:49

My trick is to find nail polish that roughly matches the finish. It's easy to apply, quick to dry, and will prevent rust and oxidation for quite a while. It's not a perfect finish match, but there are quite a lot of colors that come close.

If you can't find an near-perfect match try mixing two or three colors. Just remember the basics; with few exceptions all colors are derived from shades of the primary colors (red, yellow & blue) and black and/or white, e.g., orange can be derived by mixing red and yellow. Then you've got glitters and iridescents (whole different ballgame). But nail lacquers can be picked up at pretty low prices and if you're not good with mixing colors find a friend who is. You should be able to get a near-perfect match! One last thing, avoid mixing brand-to-brand if possible; otherwise you may have adhesion problems.

I do the same, based in the following principles: 1) the bike is already scratched anyway, so perfection is not a goal anymore (or shouldn't be, it's a BIKE after all). 2) the paint that is already in the non-scratched parts is the best your bike can get. Removing it or painting over most probably won't improve anything. 3) Bikes have a life of their own. Scratches and nail polishes add to their personality. 4) Some nail polishes are actually flashier than the original painting! –  heltonbiker Jun 5 '13 at 18:43

It would have been better if you could post some picture of the scratches on your bike to help us understand the depth of the problem.

Anyway, you can use either spray, nail-polish (quick and dirty), or actual wall paint (if you have any or nick it from the neighbours' :p ). however, if you have a lot to paint on, do it a little bit at a time. But if you use your bike once in a while, you can just do all the painting at one go.

The cheapest option is to get the nail polish. However, the colour would go off soon enough depending on weather conditions. Also, if you buy really cheap ones from Pound shop (or 99 cents stores if you are in the US), they won't last long. But, as I said, they are the cheapest and quickest option.

See this on Amazon. They should work too. The decision is yours.

Thank you everyone for all of your feedback. It has been really helpful! –  user7132 Jun 10 '13 at 21:30

Chips that are deep enough to show bare metal should be primered prior to paint. Chips that are not treated can cause more paint to flake off. The frame can start to rust and loose even more paint. While aluminum won't rust it can still corrode if exposed to road salt. I have had success with Testors brand toy model paint. I get a color as close as possible and custom mix to match my bike. If the blue isn't dark enough I add some black, if it is too dark I add some white. It is mixed in small amounts say six drops of blue and two drops of black. You can then dab it over the chips with a cotton swab or small artist brush.
