Our longest continuous field test is 25 years. As a paint manufacturer we regularly test our products. But lab tests seldom reflect real objects. That is why we choose to have third part testers making practical field tests for us. Below you find listed the tests done. And a description of purpose and length of the test. Throughout it has been shown that Isotrol Primer are giving exceptional results on rusty surfaces.
