If you are using OMNI, you will probably need 4 to 5 base coats for accurate coverage. I did my cuda in lemon twist a couple years ago and it took me 7 coats to get decent coverage. I will never use that paint again. It took me all day with waiting between coats, not to mention the extra thickness added to the paint on the car. It still seemed like it would look light/dark depending on the sun.

Restoring a car to look "only" as good as the factory made it is like getting a boob job for your wife and having the doctor make them two different sizes to seem more natural
