Wax recommendations for 2018 C?

If you want a perfect finish that lasts a long time I recommend a few steps process. First wash it throughly with a decent car wash soap. Second, you MUST clay your car, I recommend Mother’s Speed Clay 2.0. Most people skip this but oh boy, what a difference it makes to get a great result. You can feel the difference using a sandwich bag as a glove and gliding your hand over the surface while wet. It will feel like grains of sand embedded in the paint. The clay removes all of this!! Third, use Meguiar’s Ultimate Compound to remove minor imperfections, blemishes and oxidation. You can do it by hand, you must do it all over the painted surfaces. Fourth and last step, you must seal the surface using a quality synthetic wax. I use Meguiar’s Ultimate Wax, it’s actually a sealant, that means it lasts a lot longer than traditional waxes. (Up to a year).
If you follow this steps I guarantee you will have a perfectly well protected finish that looks like a million bucks. Even doing regular maintenance washes will be easier, because the surface is so smooth that road grime doesn’t stick. Doing all of this will take you about half a day if you don’t have experience, but it’s totally worth it, it’s one of those things that you do it right the first time and forget about it.
