Remember the 7 P's
Prior Preperation & Planning Prevents **** Poor Performance.
Painting is the easy bit, but if you don't do some basics like removing indicators etc (not just taping them up) then you will always look at it and think that's crap!
For a semi decent job, allow a few days just for prep work and get yourself a cheap compressor and give it a go! (you can do the inside of the doors etc with a brush)
For a really good job, get someone to remove the glass prior to painting... but it is a defender don't forget;)
Good luck and don't forget the rules! (Photo's!)
