The tank deal did not happen.
So am shelving this idea for right now.
I found out why that tank was so cheap when I got there to buy it. Had about a pound of bondo on it and it was cracking in one spot. It looked like a scratch in the picks and he said it had some scratches on it. So I thought it was just a scratch. That tank had been crushed and pulled, filled and painted. And it was done rather poorly.
So I passed on it.
