If you guys haven't tried the Meguiars "Power compound" give it a try. http://www.meguiarsdirect.com/product_detail.do?q=4759
I found this to be the best cutter, but then again if Meguiars made TVs I would buy them, they are that kind of company. But honestly this compound blows away the 3M I was using. It needs very little,it goes WAY further and no splatter all over the from the buffer, it really works well. And the paper as well Mequiars 1000,1200,1500 and 2000, it's "Unigrit" as I remember is the brand name,the best most uniform paper I have ever used.
Now I haven't touched any of the 3m that may be new in the past few years so they may have something as good. But when I found this stuff, I never looked back.
And of course Meguiars "Mirror Glaze no. 7" is the ultimate for the show car shine.
