Yes, a 12-pack. Excellent but I failed to notice what size each can is. Seems kind of important to determine if it’s a good deal or not.
Looks like 18oz from the photo.
Appears to be 12 of these-
Rust-Oleum 274232 Repelling treatment base coat-9 oz and top-coat 9-oz , Frosted Clear https://www.amazon.com/dp/B00DNQBFAW/ref=cm_sw_r_cp_apa_i_BFYbDbQT4Z961
According to that link, each box covers 10sqft
Great price compared to buying individual boxes, but check the reviews and info there to see if it’s really what you need (after some reading, it wasn’t quite what I expected)
Check your local Dollar Tree before you buy–mine has each pack of these at $1 each.
Yeah, it’s a nifty product, but suffers from being very niche - what do you need to make waterproof that isn’t already available in waterproof form?
One fun trick is water graffiti - use stencils to apply messages that appear when it rains!
