If you don't want the story of my grief over weekend, please skip to the question at the bottom.
The family dray (97 Pulsar) failed a wof on Friday - excess oil leakage

Oh - I knew it was leaking oil, I have generally despised the car since something happened about 50,000km ago, my wife coming home from work, phoned me to say something went ker-bang then whoosh, and steam erupted under the bonnet. Terminally cracked cylinder head. So I bought a used motor and whacked it in - a beauty $300 (&GST). I bought an engine crane from Super Cheap to do the job, and sold it on Trademe a couple of days later (got back what I paid for it

When people suggest replacing the rear main seal when ever you've got the engine or gearbox out, just obey them. Do not do as I did and presume that she'll be right. She was not right, about 10,000km after new engine it started dripping, then more generally leaking, then haemorrhaging, then settled down to a gusher BP would be proud of.
So Sunday, I got the old toolkit out. I didn't make my mind up whether to drop the trans or lift the motor until I lifted the bonnet, the trans is theoretically the easier option, but with these nasty wrong wheel drives, the easier sounding option may not be so easy. I lifted the motor - in retrospect it was probably the better option. The Nissan FSM says you can't do this - but it's wrong - it's written for American service technicians, not kiwis.
After about 5 hours, covered from head to toe in the black stuff, I scrubbed up (took about two hours) and we went out for a curry with some friends. We took the MX5. Stop in at mate's place for coffee, it's piddling with rain. I'd had a few so my wife drove. She's reversing out the driveway and there's this kind of disturbing scraping sound. Oops I think, that didn't sound so good. Get home, jump out and take a look. Damn Damn Damn. The front bumper seems to have scraped along a concrete wall. Only the bumper fortunately. I figure I'll get it painted, and I may as well take the bumper off myself and drop it in while I do some other winter maintenance on the car.
The rest of today I replaced the seal cleaned up a few things, and whacked the engine back in. I've run it for an hour or so, and not a drip, nothing. Back to the WOF shop in the morning - before something else goes wrong, which it will, because I hate this car, and it knows..
But I love the MX5, and it's hurt:
So the question - can anybody recommend a good painter in Chch who'll be happy to fix stone chips, the forementioned scrape and respray an MX5 bumper?
Cash payment and no real hurry.
