In a past life, I think Tiangong was a rental camper. Based on its tattoos; it has at least been to Oklahoma. I currently have a power washer I can borrow. I thought spraying off the mold would be nice, but I couldn’t stop there. Although definitely not the priority I have started stripping off the old damaged clear coat. The tang scented CitriStrip seems to do the job quite well. I’m glad we didn’t get that Argosy with the thick paint.
