Ive read about paneling and painting paneling but my paneling is painted. Taking it down seems ominous. Can I just paint over the paint? Also, the fact that its paneling is obvious by the remianing grooves every so many inches. What might I best use on these painted grooves before painting? Do I clean this flat paint (is that possbile?) since paint doesnt stick to dirt (I sense there may be tar and nictoine remains from the old man who used to live here). Id love to take it down because all the electircal recepticals are at the level of the (concrete I think) but I imagine I can just lift them out and reset them ontop of the painted paneling.
