Word to the wise. When using weld on #16 acrylic cement do not crawl inside your tank with it for 10 minutes. I have not been that high in a very long time....
I decided while I was filling up the 300, that I should go with my gut instinct and seal up the whole thing. So I drained it, crawled inside it, and sealed that bad boy up. I needed to reach the back seams, but I didn't want to take the tank off the stand. So i climbed inside it. I was so high from the fumes, by the time I got to the last seam you could have sworn I was trying to paint a Picasso painting with glue. I couldnt even smell the glue after a while. It took all of my energy to figure out how to crawl out of that tank. I couldn't even muster up the brain power to wright about it in this thread afterwords.
I let it sit for 24 hours and am now filling it up as I type this.
I also made the tops today.
