Thanks my friend! I will tell you what I personally do to achieve that shine on my finishes.
First and foremost, the body has to be primed and the foundation has to be perfect in order to achieve these kind of results. I used a Lacquer type paint to finish mine off but basically, the rule applies to any paint you choose. I wetsand my basecoat in between the layers of paint but specially if I find any large pieces of dust or debris while painting. I am using a metallic paint so you have to make sure that if you sand in between coats that you finish off with a last coat of paint, you will disturb the metallics when sanding them.
If you are using enamels, you have to wait longer than Lacquers for them to dry. I recommend buying a food dehydrator to speed up this process, they are really handy. After this, I shoot my clearcoat if needed, if you are using enamels, there is enough inherent gloss in the paint, meaning you won't need any clearcoat but if your paint is metallic and you want to wetsand and polish at the end, then you need to clearcoat.
I used Tamiya clear after shooting my basecoat. There are 5 coats of clear, shot in intervals of 30 minutes each. Make sure to go lightly on your first 2 coats and then shoot the last 3 or 4 nice and wet to the point where the paint will not run on you. I had to use my airbrush for the basecoat but I shot the clear right from the can. Make sure that your clearcoat is warm when shooting it, it lays a lot smoother with less orange peel at the end.
I like to use all of the sanding grits from my Micro-Mesh system starting with the 3200 which is the workhorse and the one you have to be the most careful. I like to use them wet but when you do this, you have to constantly monitor your progress, it is easy to rub right through your paint if you are not careful. Just keep a towel on your side and dry the car as you go through the process, you want to eliminate the heavy orange peel with this first grit. After this, I continue with the 3600, 4000, 6000, 8000 and ultimately the 12000. It is a tedious process but the results speak for themselves!
After using the polishing system, I like to use Maguiar's Cleaner wax for two reasons, it eliminates my swirl marks and it gives me a great shine at the same time. My other little secret is using a good quality chamois, it is better than using cotton or flannel which in reality will leave small scratch marks on your finish. Just rub your wax in a circular motion with your index finger and remove the wax with the chamois, I guarantee you will love the final results!
