OH YEAH !!!! do mold/rust , i've always wanted to do that. blast it white then use rust and green colors to make it look abandoned. Some sprayed in rust holes on the rockers, mold trails on the pillars, your neighbors would love it, take it to a shownshine and let some air out of some tires and put some moss on it as an accent, maybe some long grass around the tires or vines. I found an airbrush guy near me who would love to do the rust and mold.
