Whoa, I am going to stock their blockout, glad they made one what's water resistant!
We ordered a gallon of the kiwo blue but it's all messed up and stringy, totally unusable. Likely not Kiwo's fault, the supplier we bought from seems to always be a problem somehow. Might try to power drill some distilled water into it and get it working.
Been looking for a good water resistant blockout for awhile, one more step on the quest to eliminate post exposures.
