I've clayed, glazed, waxed my 2011 every 4 weeks since I got it. One bird dropping on the roof left for 24 hours and it seems to have eaten through my clearcoat. It's no longer glazed there and wax will no longer stick to it. I've never had this happen to a car before, is this typical with subarus? Water beads on the paint really well so it doesn't look like the wax is gone. Using mothers 3 step system.
How do you guys stop this from happening??
