i have used a company in peterborough, they resprayed my bumpers on my mk4 polo and smoothed them, was £100 a bumper for painting them n the job was pretty good for the money. if not then id recomend max at neil cawthorns in march, not the cheapest but u get wat u pay for. mark with the yellow AA van used sum1 in march too on his van n that was a good job.
let me no if u want numbers etc
