A long long while ago I bought a case of really good waterproofing spray for doing jackets, backpacks, shoes, etc. I am finally out of it and did not know if anyone with the hive has some leads on getting a good water proofing spray in larger sizes. Most of these smaller single item sized cans are crazy expensive and was hoping someone here might work in the textile industry or means of getting a larger amount :). If it can be found cheap enough the hive canopies could really use some coatings. Thank you.

What about just buying stuff like the liquid umbrella sealer in gallon size and using a disposable misting bottle with an adjustable spray tip?

I did something like that in the past for tent waterproofing…

oops forgot, You can also roll/paint the stuff on too… but I kinda liked the spray bottle.
