I have a nylon cape that works great but doesn't work if I decide to wear a backpack and is a sweat factory when temperatures exceed the mid 70s... that pretty much accounts for almost half the year where I live. That's why I treated a t-shirt to complement my tin cloth shorts on my summer rides. I wore the gloves and barn coat in downpours while tending my garden just to test them (looking like a dork and worrying the neighbors in +90 degree summer heat ),.. not while riding.

Actually I used the Fabric and Leather Proof (for the sole reason that I got two bottles at a remarkably discounted price) and just ran my stuff through the washer prior to treating. I also wanted to test my theory that the various 'formulations' were mostly a marketing ploy... if this didn't work well then I would try the material specific product. The FaLP came in a spray bottle but I emptied the contents into a 5 gal bucket (with about 2 gallons of water) and essentially used it like the Nikwax wash-in products... again I assumed that it would work just as well since, according to the instructions, the articles being treated needed to be wet anyway. I treated cotton, polyester and nylon articles and they all bead up water similarly.

I don't think I'll ever abandon my waxed cotton (tin-cloth) clothing but IMHO the Nikwax is a good alternative because it doesn't add weight or make the fabric stiffer like wax treating does which is great when I have to pack light for an extended or overseas trip.
