well.... I just read pretty much the whole thing the last couple of days, I have a comment to maybe help.... If I remember correctly you said the rubber liner guy told you that you could spray it on with a gun. Would that not allow for a better application ? Perhaps you could get a spray gun, borrow a air compressor if you don't have one... take the other guys left over rubber liner that he offered to ship to you.... take a couple days and just spray the crap out of it... at least 10 coats or so... I think this should really help do the job....
I agree with the concept that you were only putting on small bandade over the "wound" per say... and then when you filled it in started back again.... with a nice and fluid application of 10 or so more layers.... you should have enought coverage over the "wounds" lol to seal it for good.
I have really enjoyed your build, and wish it all the best. Since you haven't ordered the pond liner yet and won't for a few weeks as you pointed out.... plus you believe in your rubber product and said it was your application method, change your method, spray it on. and lets get some water in there....
also... maybe you can get some more of the tape you once used on the bottom and line the tank with it around all areas that maybe be leaking in your opinion... if there is another material you can use instead that is cheaper... that would work as well.... it would be great if you could just cover the entire thing and use that as "ground zero" and everything under it as just extra...
I guess Pete will have his own response to this, but if I was pete, I would be thinking:
Adding more rubber coat over top of rubber coat that is already not doing the job seems like maybe throwing good money after bad. Putting a liner in is virtually guaranteed to result in a seal, with the only points of question being the window seal and bulkheads.
10 coats of sprayed on permadri would be quite a lot of permadri, probably worth the cost of the liner or more. Also it would take quite some time to cure. Also, since he hasn't tried spraying the product down before, it will take some time and waste to get the technique right.
Using fabric and spraying from the beginning may or may not have been a more effective approach, but trying to administer (more) bandaids at this points seems unlikely to be the best approach.
