I recently bought a house that came with a Sundance brand hot tub. I've had a guy come out and fix one obvious leak that was there and since then I've discovered another leak. I've tried Fix-a-Leak on it, and it worked initially, but the leak is back. It's coming from a large opening behind the electronics panel on the side of the tub. Here's a picture:
