Thank you very much, Chris. Would Benjamin Moore Advance satin finish be fine? I checked BM's website, and saw they only have primer, satin, and high-gloss in advance series. What kind of roller would you suggest? Really appreciate your help.

I can't tell from the photo but if that is good quality paneling original to the house I would leave it alone and let the buyer decide what to do with it. When you show the house maybe put white wicker furniture in the solarium room with some bright colors for accents. If that is cheapy paneling from the '70s, can you remove it without doing damage to the walls? Be careful with this one though......Sometimes paneling was put up to cover water damage or to cover wallpaper. Ask you real estate agent about removing the dry bar. In some neighborhoods a rec room with a dry bar is a plus. Personally I would remove it. Or let buyers know you are willing to take it with you or leave it for them so they don't assume they are stuck with it and the task of hauling it out if they don't want it.

The wood paneling appears to be quality, if so, it deserves a Pro cleaning. After having it cleaned, I would suggest a porcelain travertine lookalike, in a warm shade to complement the paneling. Paint the cabinet if need be...not the paneling. Porcelain is a snap to keep clean...vacuum and use a cheap floor steamer. I have two dogs, 200 pounds and 125 pounds, so I speak from experience.

NO to painting the fireplace. Look at it. See how deep the mortar joints are? Those joints will always be dark because they are recessed, so you will end up with a checkerboard grid that looks awful. Plus, it will be very tedious to paint those joints. Plus, plus, the joints are simply dust catchers. If you had normal joints, it would be different--you'd have a subtle variation in texture. This will look like a huge mistake. See the difference in this photo. Finally: That paneling is surely applied over wallboard. It probably pops off with little trouble leaving wallboard with a few small holes in it from the short paneling nails. Easy to patch and will look better than painted paneling (which, IMHO, is a very mobile home look).
