+1 for trying to do it yourself.
I have the simoniz variable speed orbital and the 3M system (pads & cut/polish, 1,3 & 5).
I'm not a particularly hardcore detailer, and basically learned how to do this on my e30, but if you read instructions well and pay attention, you'll get great results without burning paint.
I run a canadian led kit & hid kit company, if you have any questions about led headlights or hid kits in canada or would like to check out our products please contact me here: http://absolutehid.ca
