Had the bonnet only done about a year ago (loads of stone chips, some very deep). Local guy with a single booth verbally quoted me £300, which I thought was probably too cheap.
Took him a week, between other jobs I guess, and it came out really well, except the paint doesn't quite match! Most days you have to look carefully to see it, but in some lights and from certain angles it is fairly obvious.
Still, improved the overall look of the car no end and I was pleased to part with the cash.
Point of the post, FWIW, is he honoured his quote, but said he had drastically underpriced the job and if it came up again he would want double!
