I can now remove as much rust as possible through Electrolysis, which is using water and electricity. It's a 1-3 day process depending on how well you want it done. It can take up to 5 days, really depending on how bad it is inside. I can only do one tank at a time for now, until I'm able to get more hardware for more tanks. $25 Per Tank. Each customer can have up to 3 tanks. Contact email@example.com If you would like it rushed it will be a $50 charge because I'm using higher voltage and will need nearly constant monitoring. I will also take photos during the process. Do to the lack of hardware, I will be only taking 10 customers at a time. Free stickers for customers I will do international shipping, as well as 10$ off each tank if the customer pays for shipping.
