Repair Black Tank
We have a 1 1/2 inch crack in the black tank along the bottom reinforecment ribs. I did a search on this forum about repairing black tanks and found recommendations for Plasti Mend or Eternabond tape...

Years ago I repaired my holding tank with fiber glass repair kits. You will have to drill small holes at each end of the crack. This keeps the crack from getting any larger. I then used a wire brush attachement on my drill to rough up the surface of the tank. Make sure the surface is dry and clean. The hardest part was working against gravity, plan on getting the fiber glass stuff all over. The end result was great.
