This must be cannot remain or unsightly fish eyes and white lines and spots will begin to form under the clear top coat. You could remove the residual solution with excessive rinsing, or you may simply use ReactArrest™ neutralizer. This product is especially useful when using our EasyRusts™, EasyPlate™ and EasyTorch™. ReactArrest™ aids in preventing white salt leaching, pealing, rust bleed through and other problems that may periodically occur when using these products. ReactArrest™ is a quick and easy to use tool for your metal finishing tool box.
