Resist and Defy are similar in a couple ways but very different products. We designed defy to be used as a versatile all in one, cleaner, detailer and top coating for ongoing maintenance of your vehicle.
Resist is designed with maximum protection, gloss and slickness in mind to be used as a base coating for even easier maintenance. You can pair this with ongoing use of Defy or use Resist as a topper for any ceramic or graphene based coating, spray or wax.
