My 2007 RT190P forward water tank suffered a road gash to the bottom and right (inaccessible) side, causing a serious leak. My research was not reassuring as "plastic welding" looks like a skilled job and would require removing the tank.
With nothing to lose, I tried smearing "Gloozit" glue to the gash. The leak was much reduced. It took 3 efforts of blindly slathering it on to achieve SUCCESS! So far, so good.
Gloozit is from a Canadian company and is widely available up here. Googling did not turn up an American source.
I am in no way connected to Gloozit, other than as an amazed and happy camper.
