I just bought 6.6 Nylon from Carpet One. I followed directions and applied Scotch Guard Concentrate protector. Did every thing correct with application process. I wanted a protector that beaded up but Scotchguard wasnt it. So I bought Teflon advance and applied a thick coat on a sample piece of my carpet. barely beads and just sinks in less than a second. Im assuming my carpet is just too dense.
