I used it recently to repair a crack in the seam of a doughboy sand filter. MSteve recommended trying it.
the filter plastic is about 1/2 thick. I treated the crack like it was steel. I drilled out each end of the crack + widened the crack itself, then filled it with RTV and made what I call an "umbrella" on both the inside and the outside.
A sand filter has to hold between 8 and 20lbs of pressure (depending on how often you backwash) and it hasnt leaked yet.
My biggest fear was that being at the top of the case where its kind of open, that the RTV would get "sandblasted" but all I know, is it hasnt leaked yet, and Im thinking I might not even try to hunt down another tank over the winter.
