Grey & Black tanks leak

Morning All: I am looking for some suggestions on how to seal leaks on my grey and black tanks.
I have a 1979 Jay Gull TT. The previous owners said they never used the black tank, and the grey tank had its usual workout on trips. Due to a work injury, the trailer sat for about 15 years unused. I needed to renovate the bunkhouse in the back after i took over ownership due to water damage (floor, floor joists and wall framing from bottom of rear window down, and paneling) We have used the trailer a handful of times since reno was done. I then turned my focus on to the water system, everything works although there's 1 faucet that needs to be replaced. The toilet works, and has always had antifreeze in it to keep seal in good condition. while I was checking water system I looked at the tanks and saw they were leaking out of some cracks. Any suggestions on how I can fix the leaks without replacing the tanks? (not in the budget). We generally try to get a spot near a bathhouse but I would like to be able to use my own.
Thanks in advance
Eric

They make a product called Flex Seal. ( it's like a line-x product ) that they say you can spray on and it leaves a thick rubberized coating and is water proof form both sides. I would be concerned that the vibration when moving the trailer would cause it to separate, but given its age, this will probably provide a quick fix

Here is one product. I would try this this over the spray on stuff, unless you want to go fishing on a screen door as the commercial shows! LOL

I'd just look for a used tank if you can find one that fits, or save up for a new one. Plastic does deteriorate and like my skylight, when I got one crack, soon afterwards I had 4 cracks. I highly doubt a spray product would work, but it would be a cheap thing to try. I thought you were saying the valve was leaking, that's my problem with mine, but I'm wondering if something is caught in the valve area.

I work in the HVAC field. A few of the supermarkets I work at had leaks in the condensate pans in the coolers. I have used the "flex-seal" product and is just ok. Rust oleum Makes the same product and I've used that and it was far superior than the flex-seal. Just my 2 pennies.
