I asked that question after trying to look at their MSDS page... which gave zero indication of it's UV properties...
Also, keep in mind, this product was designed as a band-aid for GM products (who, if you recall, needed billions of dollars handed to them to stay in business)
things that make you go, hmmmmm...





Their main claim to fame is restoring plastic sundamaged trim/cladding. How long would a company last whose product fails to do what they advertise. Word of mouth is going to make or break them.
