Trust me I know all about just walking away and taking time from a project Ron As a car guy myself I've been working on my 69 GTO for 13 yrs now and still have probably a few more yrs to go on it, so patience is one thing I do have

But after 18 months and one failed reseal attempt already, and now finding out there is no one that will reseal it for me, I've basically run out of options now.
This is where they mention glass. Someone asks in the FAQ's about sealing the glass window on a plywood tank and they say the tape first then sealer is the best way. The section where they mention glass is right here at this link

http://liquidrubber.ca/collections/products-page/products/seam-tape now of course you want to try to avoid any air bubbles or gaps, but the thing I have found about this liquid rubber so far (from what I can find) is that it is much "tougher" than silicone. So as long as you have the tape in the corners and seam, then seal over it with the liquid sealer then even if you did have a small bubble or gap it wont leak. To be honest I actually think for someone like myself that is not experienced at siliconing huge tanks there is much more of a chance to have air/gaps in silicone than there is this stuff. For an experienced tank builder that may not be the case, but for someone that doesn't have that experience I believe this may be easier to get a good seal with. The fact that the liquid rubber is brushed on, is tougher, and can be applied a bit thicker seems like it may be the best option for me to get this thing watertight.
It's some pretty impressive stuff, check out this link where some guy tests making a cardboard box watertight with it (there's two follow up vids as well where it still hasn't leaked a week later)
