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

In stead of dissolving a piece of ABS sheet you can also do the same with a piece of ABS pipe or ABS fitting to make a paste.
If it is a small crack you might be able to just use ABS glue painted over the crack after cleaning if up and excavating it instead of making a paste.
While some ABS glue has ABS Resin in it not all do and even the glue with the Resin in it isn't IIRC more than about 40% resin. It appears that both the clear and cream colored ABS glue doesn't have resin, but the black from Oatey does. For those reasons I did not include nor really recommend using ABS glue for a repair like this.
When making a paste just remember it takes some time for the Acetone to fully dissolve the ABS and you really want the paste to be smooth w/o any lumps. It took me a couple of days to make a shot glass sized amount of paste dissolve pieces of ABS about 1/8 the size of a pencil eraser.
