There are a ton of products on the market that claim to protect your windshield. Many people have applied waxes, sealants and coatings to their windshield, but are these glass specific products better?
Today we're going to apply three of these to my Audi S4 B9, wait for them to cure and catch the next thunderstorm to see how they perform. We'll try with and without windshield wipers to see how the different products bead. Then we'll run the wipers and drive around for a bit to see if the products survive abrasion. Finally we'll take a look at how they bead under the hose after a bit of driving.
