Door Panel opinions needed

Well I tried the different cleaners and soaps with abrasives, No luck. the dark stain is just to visible for me so Im going to spray the panels. Spent the night preparing and taping the panels for painting. Here are pics of where im at. Im going to use the same color vinyl paint but use 2 different gloss levels of thinners to try and get the slight difference in color as was from the factory. Here are tonights pics including the vinyl paint can and prep spray.
