Hi! New to this website but not new to fulltime RV living. Living in an RV/Mobile home park permanently. Have completely redone inside of RV...textured and painted the walls, cabinets (several times),put my own furniture in here-after all this is now our home so I treat it like that. One problem is that I have carpet type ceilings that are somewhat stained. I have tried all the cleaning solutions I have read about..do not work. Anyone tried painting them with good results? If so, how did you do it (thin the paint, roller, brush,etc)?
