I use this to prep glass before applying G1 coatings. Works excellent and is easy to remove; much more liquid than most polishes so a little goes a long way.

I use this on my exterior glass surfaces as well as my outdoor glass tables. G4 may be a little stubborn to work with, but it gives great results. G4 is applied by hand and you can use anything from a standard foam applicator to a pad with mild cut. G4 does a great job of removing stubborn stuck on contaminants and water marks. The final results are impressive as you are left with a glass surface that almost looks like nothing is there in low light.

Some tips to work with G4. First, clean the surface with something like G6 prior to use with G4 to remove any loose debris . Second, invest in a MF6 towel. Have the MF6 towel be lightly damp for initial break down and one dry microfiber buffing towel for fine touch up. You may not need an MF6, but the MF6 makes quick work on removing stubborn products like G4.

I used this with Car Pro Glass Rayon applicator and it did remove water spots prior to Gtechniq windshield protection application.
