This seemed like the place to post this since you guys build. I peeled off an Aquarian kick pad from my Bass batter head and it's got a layer of glue. I bought a new one and don't want to just stick it over the old glue because it will start peeling quickly. I need something to get that glue off without damaging the head and something to clean it back to it's original condition. Spending $50 on a new head is not an option. Any recommendations?
