Professional Window Film Installation Gel

Less Contamination. Better Installs.

Diamond Gel is a professional window tint installation gel designed to help installers achieve cleaner, more controlled results. Developed with hands-on installation experience and chemical engineering expertise, its water-based formula helps reduce contamination, improve film positioning, and promote faster adhesive tack.

Unlike ordinary installation liquids, Diamond Gel maintains its viscosity when used with slip solution, giving installers greater control throughout the window tinting process.

Why Choose Diamond Gel?

  • Contamination Control: Helps prevent debris from interfering with the installation, particularly in tight areas.
  • Improved Film Positioning: Provides greater control during installation and helps reduce unwanted film movement.
  • Maintains Viscosity: Designed to retain its gel consistency when used alongside traditional window tint slip solution.
  • Faster Adhesive Tack: Helps promote quicker adhesive bonding for a more efficient installation.
  • Easy Cleanup: Water-based formula makes cleanup simple.
  • No Residue: Designed to leave a clean, consistent finish.
  • Built by Installers, for Installers

Diamond Gel was developed by experienced window tint installers who wanted more from the chemicals they use every day. Working alongside chemical engineering expertise, Diamondback Supply focuses on meaningful formulation improvements that help professionals work with greater precision and confidence.

Spray Diamond Gel directly onto the glass as needed during installation. Then work your magic using your preferred professional installation techniques. It's that simple.

  • 12 oz — Convenient for mobile installers and everyday portability.
  • 32 oz — A practical choice for installers using Diamond Gel regularly.
  • 1 Gallon — Ideal for high-volume shops and refilling smaller bottles.

Customer photo review of Diamond Gel

I’ve been tinting for almost 20 years and I’ve used gels from about 6 different companies, including Importint Sauce and Avon Gel. I can honestly say Diamond Gel is hands down the best I’ve used in the industry. From the smell to the performance, I love everything about it. It doesn’t leave that messy residue on the film like other gels, it’s not sticky, and best of all, it doesn’t have that strong alcohol smell. I’ve tried plenty of products over the years, and this one definitely stands out. I’ll be sticking with Diamond Gel! 💯

Customer photo review of Diamond Gel

Working with Ryan I have had zero doubts about this gel! My first use with this was absolutely incredible! Took some time to get used to but when I squeegee a window out and I find absolutely zero contamination it is more than worth the price. If you have had any doubts about the gel you want to use try this one and it will not let you down.

Devin C. 5/5

Diamond Gel

This product is amazing I’ve used just about every gel product on the market and this stuff is far superior in every way!!! This is a must have! My favorite part about it is the fact it doesn’t disperse when you spray your slip on top of it like other gels and it leaves no white residue not to mention it smells amazing!
