I just picked up a 3401,still haven't had a chance to use it.This is my only polisher,so I got the 4" plate and 5" hybrid pads to make it a little more versatile.I know this unit will be terrific at cutting and cleaning,but my question is will it be good at the final stages of sealing and waxing with the black hybrid pad?I am just a weekend worrier,so I suspect it would be just fine.Down the road would the PE8 be the best addition for getting into the tight spots and possibly better at the final finishing stages?
