I have a chip on my alloy?

there isnt vvery much that you can do mate, if anything you would make it worse, i used to work in a tyre fitting shop and any chips, cracks etc would go straight to a specialist where they would sand it down for you weld the chip re sand it cook it and respray it, not a bad price either, the last rims i saw get done where mercedes AMG 18' and they got refurbed for about �80 each and they were in a really bad state, so i would ume that to do your rim would be no more than �50 max
