Caltex Resistall NG is a product being pushed by car dealer to be the life savior of off the show room floor 2017 Tahoe. 7 year guarantee. Applied by person in the wash booth after washing. Spray on with spray bottle, let dry, chamois and off to the show room floor for customer pickup. $899. Other products by detailers are being offered by local detailers for half the price, no guarantee. More complicated process but no guarantee. My first concern is applying any sealant on clearcoat too soon after car has left the assembly line. Second concern is how much protection do these products really provide to a clear coat?
