Flex Seal repair on grey tank.
Have any of you used a Flex Seal product to repair a crack in a holding tank?

Not on a grey tank but I've had to use it on my shower stall floor.
It held up fine for the last 2-1/2 years we had the camper. The tape is very similar to eternabond. I had to use it in a pinch and was surprised at its durability.
I drilled a 1/8" hole at each end of the crack then cleaned/prepped the floor with naphtha then cut a piece of flex seal a few inches to overlap the crack and it held up great.
Very sticky to work with if you handle it a lot.
I used the flex seal paint over the tape to blend the tape in with the bottom of the stall. Stuff worked good also. "As seen on TV" product made me squirm a little, but, it worked well.
Good luck,
Rick
