^ I have a gallon that I picked up at a great price, but after using it some, or Poli-seal (the only two I have significant experience with) for that matter, I kind of find AIOs pointless. They don't give as much correction along with finishing ability as regular polishes do. Plus, I don't leave them as the only lsp anyway. I have to go over them with a dedicated sealant or wax. It simply defeats the purpose, imo.
For me, if someone is paying for a 1 step, I want to provide the best possible amount of correction and those two AIOs simply don't cut it, hehe.
Menzerna polishes for 1 steps FTW! Just find the right polish/pad combo. Now, they just have to work on their prices!:faint:
