Not being funny, but if the alloys are just de-lacquering or have some stone chips why not so them yourself , summers coming so you'll have no problem with the paint 'blooming' due to being damp...
I know what some of you are thinking, the finish won't be as good ..... but if you take your time , it will...
I did mine over a year ago now , painted the lips silver and the face grey and then laquered them....
Ok, it wont work if the wheels are really badly kerbed , but if you have to respray them once a year , whats that going to cost, an afternoon and a couple of cans of paint ?
Minor imperfections can be filled with 2 pack epoxy filler and flatted down before priming and painting, i even had some success getting rid of my kerbing marks ....
My wheels are still good, no flaking or peeling, although i kerbed one the other day .....
will do that this weekend ! Remember , its all in the preparation , the rule of P's applies ..... Preparation and Planning Prevents P**s Poor Performance ....
Get yourselves down to Hellfrauds, pick up 2 tins of white primer, 3 tins of chrome/aluminium paint and a couple of tins of lacquer and Roberts your fathers uncle....
