My top was Tan as well, very faded. I painted it inside and out black and I love it.
I was going back and forth between Krylon Fusion and Rustoleum Universal, I am very pleased with the results so far with the Rustoleum. You cannot tell it is spray painted either. Can be done in 1 day.
5 Cans of Rustoleum Universal Satin Black (2 for inside top)
Scotch Brite Pads
3M Adhesive Remover
Duplicolor Adhesion Promoter
I used the 3M adhesion remover to wipe the wax, clean, ect. Then used the scotch brite pads to scuff it up. The the 3M remover again to clean it. Wipes it down. I then used the Adhesion promoter, sprayed entire top. Then a few thin coats of the black spray paint.
Here are some pics... Any questions let me know.
