Pay particular attention to the label’s advice on the article being clean prior to treatment.
And just like the boat tarp stuff - be careful where you apply this treatment - it can make the floor very slippery.

I think it’s sprayed on while the article is wet - after washing.
Then you set it by drying the article in the dryer? Or air dry - can’t recall.
That sounds about right. I washed a set of Scheels Outfitters rain parka and bibs, then applied this stuff. I haven't used the bibs much lately, but wore the parka over waders recently, in a couple-hour session and they shucked all the wet stuff.
