I got an old 29g from a co worker today with a sweet vintage stand that was purchased in the 70s. Stand is iron and holds 2 29s. I'm going to paint the stand but my question is about the seal. The silicon on the inside of tank is hardly visible, and I want to redo it. Is there a silicon I could vuy that's cheaper then the stuff they sell at the lfs? Also how would I go about sealing it? My plan is to scrape the bottom and halfway up the sides and seal just the bottom. Let it cure then finish the rest. Is there an easier way to do this? Could I just do it all at once? Thanks in advance.
