Yeah, it is phosphoric-acid based. I used this stuff to remove the rust patch on the back of my ram air hood. You know that area that the factory didn't paint on the underside of the hood. I think I worked about 45 minutes with the PHIX and some 320 grit wet or dry sandpaper. The rust completely disappeared and a bright metal suface appeared. After removing all the rust and all the old paint I sprayed a coat of epoxy primer on it. The hood still looks fantastic today.
