	Name	Purchased for ($)	Link	Made In
	Gtechniq G5 Water Repellent Coating	$22.00	Search on Amazon
Water repellent coating rated for four months, applied in a circular motion and left to cure 10 to 15 minutes. Tied for first overall and never once sheeted water through the wash testing.
	Aquapel	$26.00	Search on Amazon	USA
Squeeze-to-activate applicator sold in a two pack, claimed to outlast silicone-based products six to one. Tied for first overall and cleared water fastest at the end of the gauntlet.
	Rain-X	$10.00	Search on Amazon	USA
Glass water repellent sold as two 3.5 oz containers. The least expensive product here and one of the easiest to apply, and it stayed in contention through every chemical stage.
	Invisible Glass	$12.00	Search on Amazon	USA
Spray-on rain repellent in an 8 oz bottle. Simple to apply, though water began sheeting under a direct spray even before the chemical testing started.
	Adam's Glass Sealant 2.0	$15.00	Search on Amazon	USA
A 4 oz glass sealant claiming months of beading. Produced the second-slickest surface at 1.1 lb and shrugged off windshield washer fluid, but faded once car wash detergent and a scrubber were involved.
	3D Ceramic Glass Cleaner	$16.00	Search on Amazon	USA
A 16 oz spray-and-wipe ceramic glass cleaner using silicon dioxide. The quickest product to apply and among the slickest at 1.6 lb, but the least chemically durable of the mainstream brands.
	Cerakote Rapid Ceramic Glass Coating	$17.00	Search on Amazon	USA
Kit with two glass-prep wipes, an 8 oz ceramic bottle, a microfiber towel and gloves. Cures in about two hours and held mid-pack results through the wash stages.
	Chemical Guys HydroView	$23.00	Search on Amazon	USA
A 16 oz ceramic glass cleaner and coating applied in about three minutes. Created the slickest surface of the whole group at 1 lb of sponge force, which did not translate into durability.
	Debaishi Glass Treatment	$26.00	Search on Amazon
A 10 pack sold in the same style of squeeze applicator as Aquapel, and borrowing its name, for the same $26. Performance was nowhere close.
	GYEON Q² View	$45.00	Search on Amazon	South Korea
Two-step ceramic glass system claiming 12 months on a windshield and up to 36 on side glass. Over 30 minutes to apply, the longest here, and among the most durable coatings tested.
