I just painted one of my doors interior panel, the Champagne Grey. I used the PPG Omni brand, and got a tech sheet from the paint supplier, which had the info on drying times between coats etc. I was very helpfull.

I found it best, and have been told it is better to spray 2 or 3 light coats, allowing to dry between coats, rather than trying to coat it with one heavy coat of paint. That worked out best for me, and the door panel looks great!!

Take your time, do it when you dont feel like your rushed to get it done.
