I just bought a used acrylic TruVu 135. I has some scratches in it that I would like to get out before I set it up. It also has caked on salt and algae build up. Any recommendations for getting the build up off? And any recommendations for a scratch removal kit, and a polishing kit? I have looked into the Brilliantize polishing kit that TruVu sells on their website but I haven't been able to find much information about other polishing kits. Also, I would rather not have to use power tools to buff the scratches out. Thanks.
