The way I understand it, use NanoSiL if your car has minor scratches and swirls. It fills in the surface so hides paint defects and then seals it (puts a layer on top). You can think of it sort of polish step but without abrasion. If your car has deeper scratches and swirls, use both NanoFiL + NanoSiL. Think of NanoFil as sort of compound step but without abrasion.
Jetseal being a paint sealant is already an LSP (Last Step Product). You do not need to put anything on top of it. Collinite 845 Insulator Wax is also an LSP. Putting it on top of Jetseal is already redundant. So just choose either Jetseal or Collinite 845 as your last step.
