Electrical polisher

Machine Polisher? You won't get much for £50 unfortunately. Try £150. The DAS-6 Pro is a good starter and it's what I have. Have a look on Cleanyourcar website, you can get a few different kits on there ranging from £140-£180.

I've learnt the lesson on buying cheap pads and cheap polish and then wonder why pads are breaking up on me and not doing any polishing atall.

The best i have found and i use is Koch Chemie pads and polishes (proper stuff and works a treat!!!)
 
Yes that's right "machine polisher" think I'll forget about it then if they're that kind of price. Sure I'd seen some a lot cheaper and since I'll hardly ever use it I don't really want to spend much.
 
Machine polishing is hard work. You need a selection of compound and finishing polishes and pads depending on paint condition. Don't go into this half hearted and take your time.
