hybrid nano over supernatural IMO- I have both and Nano beads INSANELY- probably some of the best beads I`ve ever seen (the little one is about same price as the little supernatural)
I second uber RW
if you have to have a spray cleaner. I STRONGLY recommend Poorboys Spray and Wipe - it wont add anything to your LSP, all it will do is clean it up easily and is also very easy to use in the sun if you need to
I have tons of chrome products but enjoy Polish with Sealant (poorboys) or their Chrome Polish
edit: oh and all poorboys products are sun friendly so you could polish/seal/wax whatever outside of your condo in the parking lot
might even meet a few curious folks walking by too
