Thanks for all of the replies.
Mckenziecz, what brand of paint do you suggest? And after having a nose around on your blog, I noticed that you had a matt black MR2. Was it hard to do, and did you use rattle cans? (As that is the other route for the Micra, if I don't feel up to going down the metallic paint route) How did you manage to spray the inside of the doors and boot on your MR2? (Or did you just leave them the same colour? Cheers : )
@ Nex: The car is now over ten miles away from my Sister, so it shouldn't come to anymore harm.
