Cheers for the comments guys
Took it for a run up to O'Reillys for a bbq and it needs another wash now haha.
Approx $300 - $350 in consumables polish, clay, sealer etc and then probably another $200 - 250 in cloths and polishing pads. And my random orbital cost me $150. Seems like a lot but if you were to pay somebody to do it to this standard it would probably cost $250 or more. My sister got her car detailed by one of those Jame's Mobile Detailers and they charged $200 and didn't even clay the car before it was polished. And then they only polished the bonnet, roof and rear bar.
If you're interested in getting some gear to detail the car get on to Final Inspection in Melbourne. Damian knows his stuff and can sort you out with everything you will need. It's not much more expensive than buying the Mothers/Meguires stuff and will give you a better finish.
But remember its all in the preparation. The one item I wouldn't be without is the Blue Magic Clay Bar. I've used the Mothers & Meguires clay bars and they are tiny and take ages to pick up some stuff. The Blue Magic bar is 3 times bigger and takes everything off a lot easier. They're only about $20 more than the mothers/meguires stuff so well worth it.
