i have issues with all of the aerosol water proofers running out of propellant before the liquid is gone. i sprayed both tents and rainflys yesterday. i was hoping to have enough between the two cans to do my rain coat, but ran outta air. oh well. my coat still beads well, its 4 years old, but i only use it for canada. it packs down so the size of 2 slices of bread and fits nicely in the pocket of my lifejacket.

i used the atsko silicone this year and last year and in previous years and it always seemed to work well. other years ive used the kiwi brand stuff and i didnt like it as much. i spray a whole can on each tent every year.

the last 2 years i did the atsko silicone. when i applied it yesterday, the spray actually pooled on top of the fabric a little in certain spots. in years after the kiwi brand, the atsko has soaked into the fabric nearly everywhere.
