The day after I got my car I used the Meguire's clay bar kit. Then I put 2 coats of Imperial paste wax. I use Meguires Ultimate Detail spray to keep it shiny. I'm about to try this product one of my vendors sells called Black Cherry, it's for dark cars, and it's supposed to help with swirl marks, light scratches,etc. For the interior I use Meguires interior detail spray. For the leather, I use leather wipes from Advance (sorry Dave lol).
I've been using Liquid Glass for years. About 4-5 days after getting my beaty home, I put 3 coats on it. It is very easy on & eaiser to wipe off. What I like is that it's not a wax but a polish finish (protectant). Bugs just fall right off when hit with a water hose. If you accidently get some on the plastic in different place. No problem, wipes right off. You don't get that white spot that you have to scrub off with a tooth brush.
We use bird poop, cause the dam birds love our Inferno Red Challenger!
But really, tried Meguiar's to hard to get a clean and shinny finish in the hot sun at a car show. Went back to my old favorite! Use it on my boat too!! Turtle wax " Platinum ". Spray on micro fiber cloth and wipe, flip over cloth and wipe, done! For lite scratches, I use Tutle wax liquid, no haze
