UNO is pad-dependent, so you just apply it with what pad you need. If your paint needs compounding, get a compounding pad (usually yellow or orange), after that you'd need to polish so just use UNO on a polishing pad (white or green), and then if you want to further finesse it you can use it on a finishing pad (blue or black). Of course there are other pads not mentioned and you can make the process so much more simple by just stocking up with 2-3 of each color pad that 3D/HD sells (they're named as compounding/polishing/finishing IIRC). Or you could go the microfiber pad route (I suggest Optimum's new pads over Meguiar's due to durability) and just get some cutting discs (for compounding) and polishing discs (for ...polishing...) and you should be able to finish out LSP-ready with the polishing discs. Then just get a couple black/red/gold pads if you want to machine apply your LSP afterwards.
