My bumpers have been sprayed (rosso red, non-metallic) and they look fine, difficult to tell they were done by can-spraypaint. I am thinking about doing the mirrors but have two things to think about, 1. how the hell do you get the mirrors off (if anyone knows, please explain) and 2. wether it would look crap, I have seen one mk1 with sprayed mirrors and it didnt look great. My advice is tho, professional spraying is expensive, and unless you're getting the whole car or a large proportion of it sprayed, do it yourself. I have done plenty of jobs on mine (sprayed bumpers, removed and smoothed all those rubbing strips on the side, debadged and smoothed) hich at first I thought would be very hard and take ages, yes they did take ages, but no it wasnt too hard. Just remember with spraying like everyone has said, take your time. To be honest though, If calypso orange is the colour Im thinking of, it's a metallic paint so I guess this will be a lot more difficult to get a good finish from, I could be wrong, also, although not always immediately noticeable, the body colour will probably have faded from new, so may be slightly different to the can spray. Sorry for this huge post, but I just like to encourage people to do their own work because it's cheaper, and very rewarding when you finish and it looks great.
