The weather has not helped much but it did some quick detailing inside the new vehicle with the two aforementioned products. Gyeon is a top manufacturer of coatings and other SIO2 products. LeatherCoat was applied to all leather and leatherette finish’s. This puts a protective coating on leather without adding gloss. The trick is to use sparingly as with most Gyeon products. I sprayed LeatherCoat on a microfiber applicator and then applied lto the seats. I sprayed it on a microfiber towel. This reduces waste and streaking. It went on super easy. Time will tell him if the product has any adverse effects on the products. The look is fine. Preserve spray can be used on all plastic surfaces on the exterior. The main product was used to clean bath. UVA and uvb rays can destroy plastic trims. This gyeon product will stop that. It can be used on interior trim as well.
