Which products are best applied by PC vs hand

[jlm]

Just purchased a PC about a week ago. I've noticed that some people apply certain products by PC and others by hand for various reasons. By default, which products are "best" applied by PC? And for what reasons? Hope this is not an open ended question as I just want to make sure that I get the most out of my PC. Thanks for any input that you can provide.

You can definitely work a polish of any sort in better with a PC cranked from 5-6. You'll achieve results you could not even think of by hand.

As for a wax/sealant, you could go either way......
