ScotchgardWater Sun Shield UV Protector, 1 Can 10.5 Ounces - Pack of 4

It works, it truly works, we are so glad we purchased this spray.

Great product. Works as advertised.

I use this to spray down Game of Thrones banners that I use outside on my fence as decorations. This mixed with their heavy duty rain guard. The banners can stay out for over an entire year without fading or any problems
