So, unfortunately my car has been covered in tree sap over the long weekend and it's taking forever to clean off. It hardened making it even harder to break down. I've tried hand sanitizer, isopropyl alchohol, paint thinner. They all work but it just takes so long. A spot that is 2cm long takes like 10-15min to completely disappear after rubbing with a microfiber towel. Doesn't help my car is single stage paint... x_x Any techniques or any products to use. Almost tempted to just get a paint shop to sand down the spots and paint it after. Thinking of buying Sonax Insect remover or Nextzett bug and sap remover. Any help or tips would be appreciated!!
