i am using the Liquidvideo 1512 and was very interested in A/G removal. however, i was planning on doing the rag soak method but was leary after you a few guys said it didn't work for them after soaking for 12 hours. after holding off for and a month and a half i finally got brave and decided i would give it a try. after soaking the panel for 7 hours and the A/G came right off.
