I used my flex for the first time a few days ago and it was in the 40s and I think it turned out great. I am very happy at the results. I had no issues with the detail spray, APC, the paint correcting polish, finishing polish, and new paint sealant. The picture was taken a few days after I detailed my car. I waited to my new camera to show up and I took this picture this morning. This was the results of me using Adam's products for the first time. I was very impressed and I will continue to use them.
