I'm thinking alternate uses. Rather than clothing, I wonder if the stuff can be applied to other items such as exterior walls, roofing,
fence posts.
There is a product out there with a name something like 'ultra super dry'
(found it) that repels mud and slop when applied to surfaces. I did the math on what it would cost to treat my house and found the price prohibitive.
This sort of product would be handy for protecting some outdoor items if the price is right.
How about a canvas awning, a tent, stones in a walkway, work
boots or glass in a
greenhouse?
Can it turn a regular jacket into a rain suit?
Will it keep water off the driveway or a vehicle, especially in freezing weather?
I'd be curious if the product will leach out of the item to which it is applied and if there are any environmental concerns.
The
ultra everdry stuff runs a hundred bucks for a couple quarts.
If this fabric softener comes in at 10 bucks a quart, it's affordable for experimentation.
