| I have used a product called Geoseal in the past on actual cracks in poly water tanks. When they were cracked we drilled small holes on either end of the crack and also along side of the crack and first stitched the tank with mechanics wire then painted on the Geoseal with a brush. The first tank we did that to was a stationary water tank for spraying and we never used it on a trailer again(didn't want it moving and shaking) but it lasted another 5 yrs like that. Have done several since then for similar purposes and have had decent luck. We got the Geoseal at the local True Value, I know they still have it, we used some last summer. | |
