[VAC] Re: Blackwater Tank Repair

[Robert Gill]

I have some of the same problems with mine that you describe, although mine's not as bad. What I'm thinking about doing is basically wrapping the entire tank with 181 fiberglass cloth using a good epoxy resin as the matrix. My biggest concern is properly sealing the vent opening and the discharge. So my tank will basically be the mold for my new tank, I just wont remove the mold.

I have recently purchased a '65 Globetrotter and I'm in the process of a total restoration. I have all of the interior and a large section of the rear floor out of the trailer now.  I've been reading the archives to catch up on the topics discussed and to avoid posting redundant questions.  I came across a thread about blackwater tank repair started by Harvey Barlow (I believe) and haven't seen any real conclusion to it(perhaps I missed it).    My blackwater tank has several cracks in it around the intake and the discharge.  I priced a replacement from InlandRV at $445. Seems a little steep to me.  I'm still waiting on a price for an A/S replacement.  I'm adept at working with epoxy and fiberglass, coming to A/S restoration from  a boatbuilding background, so I initially thought I would repair or rebuild the existing tank.  I was concerned about one reply that said that epoxy wouldn't adhere to a polyethylene tank. Is that what the original tank is made of?  Doesn't seem to be.  So, bottom line is,,, does anyone have a final verdict?  Can you repair these things?  If so, what is the best method?  Or would it be better to just fork out the money for a replacement?  Or have one custom made? Harvey, I saw that you went with a stock polyethylene tank and modified it.  How'd that work?  Are you happy with it?   Any advice is appreciated.   Jason Guynes Livingston, AL 1965 Globe Trotter Get your FREE download of MSN Explorer at http://explorer.msn.com
