300 Gallon Acrylic Tank Seam Leak

[d101123]

I have a 300 gallon tank that hasn't been used in a while and leaked from the seam when I did a test fill. The seam area that is leaking is about 2" long, but you cannot see any crack or gap. The panel is slightly pushed in enough to feel a small imperfection if you run your finger on the joint where the leak is. Would using Weldon 4 and/or 16 take care of this and could I apply it to all seams along the inside of the tank before filling??

Any tips on applying the Weldon would be appreciated if that is a good option!

Got it, thanks!
How many pints of 40 would I need to do all 8 corners of a tank with the dimensions below? The tank is about 20 years old and hasn’t been used in about 6 years.

L 8’
W 24”
H 24”
1/2” acrylic

4 then 40

I’d say 2

I agree With Lepisosteus two should be enough for tip and pour.
