Hello , I need to know if there is a vinyl that will withstand 150 degrees and it will go on an open tank that has citrus acid in it. they heat the citrus acid up to 150 to clean copper headers with. during the weekend, it will be shut down and then started back up the next week. I need something that will last. They need instructions on the side of the tank for mixing procedures and they would like it put directly on the tank. Any help appreciated.,,Paul
