Has anyone had experience with the Cobra Deluxe MF versus the MF's from Pakshak? I'd like to pick up a few more for drying and I like the prices at Pakshak. I have a few of the Cobra Deluxe Jr. from Autogeek and they work quite well for drying. I see some feel that WW's can leave marring, so I'd like to get a few of the MF's from Pakshak if they will work as well as the Cobras.
