Nope, never tried it. I`ve used both Permatex and Rust Oleum`s stuff and what I didn`t like is that it wouldn`t bond to either clean metal or surrounding paint. I know guys who have used both SEM and Eastwoods converter with success, but I`d rather just stick with the Encapsulator unless it`s really nasty.
BTW, POR 15 says no topcoating unless you use their proprietary Tie-coat primer and I did have some delam issues when I tried to cheat. KBS states that there`s a "window" in the drying process when it will allow topcoats or primers to bond. I`ve done a bunch of undercarriage parts that way, shooting satin black over KBS on my Camino and they`ve held up for 8-9 years so far.
