Porcelain toilet tank with hairline crack, how to mend it.
"Dear guys here, you know God is really trying (as in trial) me for whatever bad thing I did, whatever - hahahaha!
Tuesday morning (it is now Thursday morning April 19, 2018 as I write this message) I woke up and heard water dripping in the CR, so I investigated.
What the heck! The water closet set on top of the rear part of the toilet bowl has developed a hairline crack on the front side.
Why God chose me to meet this kind of a trial, He Himself only knows.
The hairline crack starts from the top edge and stops just short of 3 inches to the bottom of the tank.
I still had some leftover from a roll of Ace Mounting Tape with double side adhesive compound, used for sticking of light plastic wall clocks to walls.
I thought it was possible to just paste the remainder tape to cover the hairline crack.
So I drained and wiped up all the remaining water from out of the tank, and left it with the cover off for some eight hours, to dry out the interior.
And I applied the Ace tape on the hairline crack.
No, that did not seal up the hairline crack.
Next bright idea: I went to the neighborhood hardware and construction supply outlets to inquire about duct tape.
Yes, they have, only one kind and it is 3" x 25' long; but I don't need all that length.
Besides it does not seem to be water-proof either, though it has been praised to the sky for all kinds of even the most outlandish needs, like stopping bleeding from a fresh accidental cut on a leg.
So I read about elastomeric water-proofing paints, etc.
What do you guys know about any possibility and also genuinely lasting repair of this hairline crack?
Otherwise it is going to be replacement of the water closet and accompanying fixture, and that is a most burdensome task and loss of money - another trial from God.
Dear God: Please, don't take me for a Job, please!
What do you guys say, should I buy a small can of elastomeric water-proofing paint which is water soluble, and apply it to the hairline crack?
What is your knowledge and experience apropos this problem? "
