Hmm.. i must have a GOOD NicSand MF towel.. i used mine on the paint, and checked under the 500 watt worklight, and saw no swirls, no marring.. just a few stone chips, and light scratches the Scratch-X couldnt fully remove..
i only have ONE NicSand.. i use it to remove the majority of the residue, and then follow with a Viper MF to remove the rest, and finally with a MF Scrubbing towel to get whats left.
