ACDelco Rain Repellent Treatment helps make glass surfaces water resistant while significantly optimizing driver visibility.

Originally developed for the aviation industry, it causes rain to bead up and roll off the glass.


Is this product a one-time treatment?

No, this product can possibly last for many months, if instructions are followed properly. If the performance of the product appears to have been reduced, make sure your window is clean and re-apply the product if necessary.


Do I need to use specialized cleaning products for my wheels, tires, and other exterior parts every time I wash my vehicle?
Yes, specialized products can help keep your vehicle like new – these products often contain unique materials designed to work on the many surfaces found on the vehicle.


• Make sure to thoroughly clean and dry the glass before application.


• To apply, hold the applicator with the pad down and level. Squeeze the wings to release the product. Use immediately – wipe entire glass surface with applicator pad. One applicator will treat one windshield or two side windows. Wipe the glass clean with dry paper towels.


• Even if you are not able to immediately wash your vehicle or vehicle part(s), wipe off dead bugs, bird droppings, tree sap, and other visible contaminants as quickly as possible to minimize damage to the finish.


• It is especially important to keep your vehicle exterior clean in the winter. Abrasive road salts can cause significant rust and corrosion if not cleaned off regularly.


• When washing or cleaning your vehicle or vehicle part(s), do so in a shaded area. If the vehicle or part is hot, soap and other products will dry too quickly, staining the surface and requiring another wash.


• Pre-soak your vehicle or vehicle part(s) to remove heavy contaminants.


• Always rinse your vehicle or vehicle part(s) thoroughly.


• Use a different mitt/sponge/cloth/etc. to clean each part of the vehicle (exterior body, wheels, rims, etc.).
