I was in one of my auto parts stores the other day and noticed something I hadn't seen before. I saw that DupliColor has a product named "Rust Barrier". I was wondering if anyone here has tried it and what their thoughts are on it. How much was needed and how it's performing. I had talked to my paint guy about POR 15 and he told me only a 1 qt. can was needed for a frame. I looked at a DupliColor video and they said 2 cans were used for the frame. I thought maybe that was for sales. :wink2: Also the MSDS stated that the Rust Barrier was pretty benign compared to what I have seen here about POR 15.
