Hey mate,
It would have wanted to be a good job for the price I paid.
I actually I have no idea who did the actual repair. Because I have a friend of a friend at a local Bob Jane I organised with them to have the guy they use to fix up the wheels before they put the new tyres on.
Basically he's a guy in a van who comes around and does them on site.
In regards to spraying, it looks as if it has been matched to colour, as there are other parts of the rim which haven't been sprayed, however I can't tell the difference between them.
Your best bet would be to try your local tyre fitters and see who they recommend. If a common name starts to come up then they're probably the way to go.
Sorry I can't help you out more than that.
Cheers
Trent
