Things are really starting to fall in place right now. We haven't filed for a patent yet but we have the paper work ready to go once we get the next round of test results back. Patents aren't all that people think they are... you have to have the money to defend your patent should somebody decide to copy your stuff.
Lots of time and money spent only to find out that the people don't have jack crap to begin with or they have their assets so well protected you don't get squat from suing them.

But we will file for one anyway.

You are welcome for the mentions and some day I intend to give you a proper answer when I have the time to go and cite the proper research.

The next round of testing is scheduled for 06/13/19 for the permeability testing so it won't be long before we find out just exactly how much water is being repelled. Right now those other types I mentioned boast about 70 to 75% reduction in water absorption; we should blow that number out of the water (pun intended) but you just never know until you have the results.
Keep your fingers crossed for us if you will.
Thanks.
