“We have not found any other tank liner that has the longevity nor the resistance to chemicals including acids as the Heresite P-403L. It not only protects, but unlike many competitive brands, it will not contaminate the contents in the tanks. I have a current customer that we are working with that got 20 years of service storing acid based liquids before their tank liners with P-403L needed to be recoated. Now that’s what I call protecting your investment. ”
