Picked up this used 180 gallon from a member of a local fish forum in August . Tank has been stored outside, standing vertical on side exposed to direct sunlight. Glass appeared intact, but the external silicone seal is shot. For $100 I was willing to take a gamble, especially since this tank is going into an unfinished basement. So, with the following week off from work, I rolled up the sleeves and started, scraping, masking, siliconing, and cleaning.
