I am interested in buying RIM + Tire Cleaner (two in one), and a quick wax (for exterior shine). There are a bunch of products, that confused me. Can you please share your experience, for a longer lasting, better shining product that requires less effort.
Thank you.

i think you might want to post in the auto detailing forum. that being said, i use McGuires Gold Class for a quick liquid wax.

If you wheels are coated, then I would just use Simple Green or Meguiar's All Purpose Cleaner. Either works wonders and will do a fantastic job at cleaning. As for the quick wax, that all depends on what you are trying to accomplish. If you already have a waxed surface, and just want a booster wax to maintain durability, than Meguiar's spray waxes work great as well as many others from many other companies. If you are looking for an easy wax to use, then perhaps Meguiar's ColorX or X-Press Liquid wax (bought by the gallon, but still pretty cheap at only $26) dry virtually as fast as you can apply them and are really easy to remove. ColorX is a cleaner wax which may help boost the shine a little bit if you don't plan on polishing beforehand.

For the exterior, you might want to try Meguiar's NXT spray way. It's easy and commonly available. I sometimes use Optimum Car Wax, which is also a spray, on top of an acrylic sealant. You would have to order the OCW.
