Thanks for the questions. I'll try my best to answer them here:

Most conventional interior tank sealer can be removed with any good paint stripper containing methylene chloride. These types of strippers can indeed be found at Lowe's, Home Depot, Ace Hardware, etc.

If you're working on a steel tank, it's just a matter of pouring the stripper into the tank and rolling it around to allow the stripper to coat the inside and cover that old sealer. While wearing safety goggles and gloves, rotate the tank occasionally to allow the stripper to soak and begin melting that old sealer. After some time, drain out the stripper, but catch it as you may need to reapply later. Use a rag or towel around the opening to keep the water from splashing out and up at you, hose out the inside of the tank with a high pressure hose, if possible. Most if not all sealer should be removed. If not, repeat the process.

Once done stripping out the old sealer, just follow our tank sealer instructions which come with the kit.

It's highly unlikely any of these products could "cause" a leak in a solid tank.

Hope this addresses your concerns. If not, just post again.

Thanks
