I did not sand mine. I did wipe the inside down with a wet rag first to get any dust or any dirt, then went back and wiped again using alcohol to get any greases that I couldn't see. Then I used 3 cans of flat black paint and then went over that with 3 cans of dupicolor. The dupicolor was more expensive than the paint and once you have the black base coat, you don't need to completely coat everything 1/8 thick with bedliner.
You could probably do the whole thing with 4 cans of spray paint meant for plastic if you wanted. It wouldn't be as rough to the touch.
What is the best method for painting the roof interior? Any suggestions
What I did was take a red scotch bright pad and scuffed the entire surface really well. WARNING, you will use alot of elbow grease so a good beer break might be in order after you finish stuffing it up! Then mask up your windows and anything else you don't want sprayed and go to town. Enjoy

I scuffed mine up a little with a pad and then just used normal spray paint. Its been on now for about 4 months and the only places its coming off is where its rubbed when I take the freedom top off. I did take all the additional hardware off while painting.
Super easy and if you havent done this yet youre missing out. It makes it look 1 billion x better on the inside. Everyone comments on it.
