What are your thoughts on this thread? Results look very good and I'm only doing the front bumper which is actually quite a small surface area and only the sides make substantial contact with the existing colour for comparisons.

That's exactly what you need to do...good tutorial there. But I would say start on a small piece and get your spraying technique perfected.
Dude, not saying its impossible, in fact my friend did my old e36 front bumper for me in my back garden last spring. The finish you can get from a rattle can is quite good, but you have to be good with the controlled strokes of the can. Whilst he was doing the bumper I was doing the wing mirrors, and trust me, I had to go back to primer 4 times, because my spray technique wasn't up to scratch.
Didn't really matter on the mirrors cos they were a small item, but I would have screwed if I had to flat the bumper back that many times, because of runs and splits just because of the size of the piece.
Prep is everything, you need to make sure that the piece is SMOOTH to the touch even before you start...and be prepared for sanding, painting, sanding, painting, sanding, painting, sanding....you get the pic...
Also what colour are you painting. I'd assume that the white is fairly easy to colour match, but when it comes to metallics, it's a lot harder.
