TopCoat® Gla-C®

Many materials like vinyl, acrylic, isinglass (plastic glass on jeep soft tops, on boat canopies), lexan, and window film get damaged or dry out due to harsh chemicals in traditional glass cleaners. Knowing this, we developed TopCoat® Gla-C® as a water-based formula, safe for any material, and our environment. TopCoat® Gla-C® not only cleans, but prolongs and protects these sensitive materials, maintaining them in like-new condition for years to come. 

TopCoat® Gla-C® uses MycroGlide™ Technology, this technology chemically fills in the microscopic pores of the glass to a point that significantly reduces surface tension and friction, creating a smooth barrier that keeps the glass cleaner, longer. TopCoat® Gla-C’s® technology is so revolutionary, any treated glass can easily be cleaned with a simple wipe from a microfiber towel!

The only product that safely & effectively cleans, maintains and protects window film, acrylics, & isinglass. Without cracking, yellowing, fading, or peeling.

    Gla-C Works Great

    I cleaned my car windows for the first time with Gal-C recently. It was very easy to use and made the windows crystal clear clean with no streaking. I just sprayed it on, wiped it in a circular motion with a micro fiber towel to remove the dirt and then polished it with a second clean microfiber towel. I’ll definitely buy this again when I run out.

    AWSOME!!!

    It warmed up enough here for me to detail my car and used Gla-C for the first time, it was so easy and there were no streaks or smudges on my windows, I waited till early evening to look at my front windshield again so I could see spots I missed and was able to entirely clean my front windshield spotless
