I took my dog for a ride in the S today (yea, yea, bad idea). He slobbered everywhere. I tried a damp microfiber on the doors and sills but that didn't do much. So, I tried both 303 Aerospace Protectant and Meguiar's Natural Shine and both of them streaked really bad. I buffed a lot trying to get out the streaks but they still look bad. Any suggestions for a product that doesn't streak?
