Top job that. Gaz doesnt even do this as a job full time. He told me he does it for pocket money.
When i got my rear arches replaced ages ago and also got a full respray. It took 3 months and i could see signs of rust coming back through.
Ive had my cossie back from gaz over a year ago,the car has sat through 2 winters on the drive and the arches are as good as the day Gaz did them.
