Read a couple of posts recently about which polish to use and the lengthy process some of us go to to get that ultimate shine. Now I got an electric polisher for my B'day and now I'm hesitant to use it. Read in a previous post that polishing in circles will give a spiders web effect especially noticable on a black car such as mine. Given that the polisher obviously goes round in circles, I am going to get the ultimate spiders web if I use it? Has anyone used one and got good results?
