i painted my ineterior and it looks great...ill try to get a pic soon.
All i did was take pieces out, clean them obviously with any kind of mild soap(dish soap works well) and i painted using tremclad available anywhere. I painted 8 light coats of colour( i used white) and then 3 coats of clear. I have no bubbles or fading and its been 6 months. Only thing i regret is i wish i painted differently. I painted the centre of all doors( i have a 4dr) white and the centre console white and the rest of he dash and doors in blue. Looks great but the white gets dirty easy although with 3 coats of clear it is easy to wash. Up to you i think it worked out fine for me and a few of my boys.
