SS holding tank and urine don't mix well. Plan on another round of Flexseal or a new plastic holding tank.Had a couple of small pin holes in the weld seam on our SS holding tank. Purchased the stuff at HD. Sprayed on two or three coats. Leaked stopped. That was a year or so ago. Pricey, but it worked for me.
I’ll drill some holes in the hull below the waterline and give you a full report on how well it works.
That's me ! And that's why I have to go back and update my post about water treatment. I'm up too late, but my brain goes to bed early.Perhaps it is too much like those late night sale commercials aimed a the 2AM crowd.
