Optimum Opti-Bond Tire Gel is a thick, water-based formula for use on tires, wheel wells, interior and exterior trim, vinyl, and dashboards. It will produce a durable, high gloss shine that is not greasy or attracts dust. Opti-Bond contains no petroleum distillates which are known to crack rubber and vinyl. It contains advanced UV and ozone protectants to shield surfaces from sun damage and environmental pollution. Rubber and vinyl surfaces will remain supple, flexible and retain their color with regular use of Opti-Bond. 

Opti-Bond Tire Gel can be applied a couple of ways:
 
You can wipe it on with a foam applicator, just like a traditional tire dressing.
The other option is to dilute the gel 1:1 with water and apply it with a spray gun and air compressor. The gun will deliver a fine mist over the tires and wheel wells. This is a great option for professional detailers and garages. Wipe away excess tire gel with a foam pad or a lint-free towel.
