Invisible Glass can only be shipped via ground. Invisible Glass is a flammable liquid so it cannot be shipped via air. This excludes a lot of international & island locations like Hawaii.
It took me by surprise that Invisible Glass would become my glass cleaner at OGHQ. Michele and my mother have been using this stuff for the house windows forever and it never crossed my mind that I should try it on the vehicles. This is an alcohol-based cleaner with no soaps, detergents, scents, or dyes, which can leave streaky residues. This is a non-ammonia product so it's a tint safe product. Pair this with the Glass Cleaning Towels and you're good to go.
