Contemplating selling off the Cirrus... biggest issue is Pine Sap... huge tree 3 stories up, hangs over my parking space. I've been cleaning the drips off the glass practically daily... let them dry & use a razor blade scraper, come right off.
On the paint, I've tried commerical products, WD40, paint thinnner & others with no luck. Finally success! I've been using rubbing alcohol on small pieces of rag. Focus on small areas & one by one the drips dissolve with no damage to the paint. Areas need washing after they are pine free. It's a long process to do the whole car.
