Hi, so I see on many bottles of products, videos, and articles stating that it is best if detailing steps were done in the shade but I do not really understand that. Is it just because of the heat from the sun drying out the products, and affecting the paint in a bad way, or is there an affect on the products due to the actual sunlight, like UV rays? I am very confused about this. For example, if I am washing or polishing my car in the shade, but the sun shifts and a part of the car is exposed to the sun's rays, is that okay? I know that people say washing the car in the sun is bad because the water can dry and leave water spots and that is why I was wondering. Also, I live in Toronto, Canada so it is not always very hot here. Since it can get quite cool here in the winters, or even when it is mild in the spring and autumn I am wondering if it is okay to detail in full sun? Shade is very hard to come by at times, especially when I am trying to do a full day detail on my car and my garage is not that big. Thanks in advance for any help you can provide!
