Honestly its childs play, all you need is some very basic kit, like a small 3" air sander a die grinder and a small smart repair gun and your away, You can get all the kit you need for under a £100 unless your a brand snob like me in which case might be a bit more.
Primer and lacquer and activator you can buy in 2.5ltr and will last forever, then just ask your local paint shop for a tenth of what ever color you need which we pay £6 for.
Then its the same for every wheel rub down small fill if required primer top coat and then clear.
I would be the first to admit we are by no means pro but to date no one has ever said hang on they dont look like they have been done by a pro they pass every time and costs us less than £20 a set in materials and about 3 hours work.
will not be for everyone but for us works well
