Repairing Paint Chips on Alu Frame

put a sticker on it. My bike's mostly stickers now.

Another vote for car touch up paint, if you sort of blob it into the chip it fills as well as paints.

If you're going to raid your daughters make-up I'd mention it to her first, you don't want that awkward "Dad, what are you doing ?" conversation

Hi, I would go along with Joemmo. I have always picked up a ready mixed touch up pot from my local auto body shop suppliers.
I go for the ride and show the guy there the bike which he uses a colour chart and matches what I want almost perfect. The little pots cost £2.20 each and the paint is self hardening basecoat/laquer finish. Great for 'dotting on'.
There will probably be one of these auto shops on your nearest Ind estate.
Hope it helps.

Trikeman.

car touch up paint is another alternative although it's difficult to get an exact match just trying to use the colour on the lid alone. Still, if it's silver then it shouldn't be a problem

nail varnish is the one

Can't recommend anything to fill the chip but to cover the chip with a colour I just use nail varnish. It's hard wearing (just look at what women do with their fingers ) and there are thousands of different colours readily available and at affordable prices.

The only issue you might have would be some shops might object to you taking your bike inside to compare colour scales

To fill the chips I recommend Araldite (not the 5 minute version) mixed with fuller's earth as a thixotropic filler. However, even after judicious application of wet'n'dry, that's only ever going to get the surface smooth. In order to completely mask the offending ding you will either need to have a good match for the existing colour or think about overpainting, perhaps with hoops.
