Hi Bob.
Yes, I finished it up. I let the vinegar sit for a little over two weeks. At first I was turning the tank every few hours to ensure I "treated" the whole tank then after about two days of this I let the tank sit for about a week without turning it. Then I turned it and let it sit for another week. After this was done it appeared that the liner was loose (I had many large flakes floating around) so I emptied the vinegar and then hosed down the inside with pressure (just hose pressure). I then dried the tank with a blow drier and then started with the kit that I had bought from POR-15. I followed their instructions. Before I put the paint in the tank I noticed I had a little flake of liner paint sitting in the crevice near the petcock outlet. I couldn't retrieve it with a screwdriver or a piece of wood so I made up a fine suction hose using tubing that I attached to my shop-vac nozzlle. This did the trick.
I applied the tank liner paint following the instructions and it all worked well. The tank has been sitting now for about 10 days and is ready for use. I did do some damage to the exterior paint and I will have to repair it or repaint it if the repair won't do the job...Other than that the re-line job was successful.
Anybody want 24 litres of used vinegar?
