I don't know Ulf. I've never used it myself (I've got a buffer with compounds) but have heard good things for many years about its predecessor, Zoop Seal. I'm hoping someone with real experience will chime in here and set us all straight. :-D
They closed their business but there seems to be a new company representing this product instead. After looking at the pics the product seems magic!! :glasses7:
I will shoot them an email so I'll keep you updated.
