We've started in on the "to do" list; toilet's repaired *yay!*, engine's been tuned up, and since it's finally above freezing here in the KC area we though we'd start spiffing up the exterior. What the heck is this coach *siding* made of? I've spent a couple of hours on this with nothing to show for it! After we remove the grey gunk the previous owners used, what would be best to patch with? Clean? Shine?
