Next door to Alliance Rim repairs is A&S powdercoaters... no prizes for guessing who Alliance used to use while in Oz Park?!
I had my track rims powder coated here a couple of years back for a very cheap price (cheaper than Alliance sending them next door and adding their fee etc!)- did a set for JimmyS in 'black onyx' at the same time as well. Have had no problems with wheels or finish since- and they've taken a ton of beating trust me!
