And the name of that product would be?????
Sorry, when I wrote my comment I didn’t feel like going out to the garage
PPG DX520 but that was years ago. Might now be SX520. I haven’t purchased any in a while. I also use it to remove rust from small hardware bits, nuts, bolts, etc. I soak them in a glass jar. You have to monitor the process. The stuff is pretty aggressive. It makes bubbles when working. When done I screw the cap on and save it until next time. Beware of sticker shock - $35 for a quart!
