I have used neverwet and liquid off and liquid off beats neverwet hands down for use ability. I sprayed a $20 pair of convertible pants I got from Costco with this stuff and threw them in the dryer and now they are super hydrophobic! Beats paying $80+ for water resistant north face hiking pants and had plenty left over to treat other items.
One thing of note though I did have to spray the pants twice though as apparently I missed some spots as the pants were mostly hydrophobic after the first spray except for a couple spots that got wet. My recommendation is spray, dry, test, spray, dry.
