No seats, why would you post an item on ebay and then plain refuse to talk to the winning bidder about collection and payment

And the coilovers I paid for over a month ago have still not arrive

So my wheels have been in my shed waiting to be fitted for over 4 months now
On the plus side however, I have a full Vento front end sitting in the shed together with a pair of colour coded bumpers and two straight wings waiting to be smoothed and painted...
So, I want to paint myself, what would you all recommend, rattle cans or spray gun and compressor? How do they compare cost wise (besides the cost of a gun and the rental of a compressor of course) and finish wise (bearing in mind I've never used a paint gun)?
