Nice thread, Ive done lots of these when i was a panel-beater.
I used to be able to do a full set in a day in work no problem then put the tyres on the following day obviously.
Its not that big of a job quite handy and if ya have no or little experience Id recommend attempting the repair ya cant go too far wrong after the repair clean with thinners and I found (Wurth) aerosol primer worked fine on wheels thenget a pro to spray them up for ya if ya dont feel confident.
I used to use a clean silver with very little metallic in it and tint it accordingly to what colour ya want.
