One possible cure is to use SEM Plastic Prep spray followed by E6000 adhesive. No guarantees, but it has worked on my tank issues so far. I have had a persistent leak in the gray water tank on the Royale for as long as we have owned it (11 years and counting). I tried most everything. The special black tank epoxy stuff appeared to work for a while but the flexing in the outlet pipe on the end of the gray tank eventually caused it to fail as well. Recently I tried the cocktail of SEM Plastic Prep followed by the E6000 and so far that appears to be holding well. The E6000 is used like a caulk, with a thick bead built up all around the pipe in stages. Too soon to say whether it is a long term fix, but so far so good.

Thanks Emery. I'm attempting a repair. Sanded 60 grit, wiped with alcohol. Doing Loctite plastic bonder epoxy, 2 coats, then Gardner leak stopper clear patch in caulk tube as that's flexible, then going to spray area with Mighty Sealer. If that doesn't work, then sand off and go to Terry the plastic welder in Chesterton In. Camping World would only replace ( and didn't get to the 77 GMC part) and General would apply some patch so trying that myself. Need a new tank but wish we had a Jim K by Chicago. Polypropylene has that Teflon like property
