Ok, so this weekend I washed my car with the sample of Ultima Paint Guard Plus. I washed the car while it was cool and in the shade. I must say I was disappointed. This stuff did not rinse off very easily and it left some water spots. Previously I had washed my car using Sonus Gloss Shampoo, and this stuff was great, here are some pics from that previous wash using Sonus http://autopia.org/forum/car-detailing/97582-what-do-you-think.html Has anyone else had a similar experience with this Ultima product?
