Help needed!!! I have bought the 3 stage #1, #2, #3 Novus product and can not get it to remove the scratches in my 150g acrylic. I watched a youtube video ( a guy recording from his IPHONE he sanded then used PlastX) tried that and still didn't get the straches out. It did word WAY BETTER than the Novus though. I would call the scratches deep at all, medium at most. I am about to pull my hair out. HELP NEEDED PLZ!!! My wife is going bonkers and giving me hell spending money on this tank and can't even use it. I know you have been down the road and can imagine the pain I feel (more from the empty tank) people and LFS are saying its not that hard to do. the Novus video makes it look ABC. What am I doing wrong???
