As a "Zaino-Zealot", I'd have to recommend "guess what?". All of Zaino's products may be applied and removed easily by hand. I have used Z-PC Fusion Dual Action Paint Cleaner Swirl Remover by hand, and it worked well cleaning and removing swirls and came off easily. I'd also suggest Zaino's All In One which I've also used by hand and is very easy to apply and remove. In fact, I have an Excalibur which is all nooks and crannies with louvres, etc so I have to do it by hand. (See the pics of my Black Beast in yesterdy's "Click and Brag".) My other cars have lots of open surfaces, so I can use my PC on them, but it's actually quicker and more economical to apply sealants by hand. I can apply Z-2 or Z-5 pro on our LS430 in about the time it takes to get out my PC, unroll the extension cord, plug it in, and put the appropriate pad on the PC. BTW, I'm a 67 year old chubby guy with rusty coronary arteries.
Carnuba is a great wax and can be applied OVER any sealant, but waxes do have a limited life, usually a max of several weeks, while most sealants last at least several months. Zaino does seem to have the edge when it comes to durability.
You could help all of us to give better advice and recommendations if you were more specific as to your location, and gave information about the car and the color and condition of the surface.
