Today I got the good old tank from my aunt and uncle. That baby was built in 1968 and was in service for about 7 years. At that time those tanks were hold together by an iron frame and cement to keep it leakproof. After all the time in shelf I think that there is a big chance, that it will leak.

After inspecting the tank, I figured out, I'll break the glass when I try to get it out off the tank. So I try to clean the messy work on the outside, and did a soft grinding on the iron frame to prepare it for painting tomorrow. 

Tomorrow I'll get the paint and hopefully I will receive my silicone, so I can seal the tank from the inside. I hope that stuff will dry out very fast.
