I bought a clay bar kit which consisted of clay and detail spray, some optimum no-rinse wash and a small bottle of poli-seal. Did a 4-step job: wash-clay-wash-poli job using microfiber cloths (no electric buffer) and the results are superb. Optimum's no-rinse car wash works surprisingly well even though it doesn't seem like it will, and the shine you get with poli-seal is as good as or better than any of the other products I've used (zaino, meguiars, mother's).
Took me about 3 hours total including the clay bar process. I'd highly recommend optimum's stuff for anyone that wants an awesome shine but doesn't want to apply multi-step products or go nuts with all those cleaning supplies out there. I like having a shiny, clean car but I don't want to spend a lot of time getting it to that point.
At this point I wash the car when needed and I can apply more poli-seal (although it's not necessary to apply it each time you wash the car)...so it's effectively 2 steps and probably an hour of work. The no-rinse is great because you can wash the car in a garage any time you want, and using warm water makes it really easy to get bug splatter off.
