Masterseries is an upgrade from POR-15. Company was started my the chemist that worked to develop POR-15 who left and started his own company to sell a better product when POR-15 cheapened their formula. You don't see hiway bridges or other large high dollar projects using POR-15 where the true test is. Bridges get salt and brine dumped on them all winter long, year after year. Classic cars are get done, then babied. Masterseries has a wide line of products to address various situations. I would never apply either straight over rust no matter what they might claim. Do the work and get the best job when it's easiest... a bare frame
