Review on WG-3004 Exterior Trim Sealant by Wolfgang Concours Series - 4 fl. oz. by Loren Rindfleisch

Be sure to wear gloves when applying! Also, I cut the rag (old t-shirt, etc.) into a very small piece (5 x 5 inches); This way the rag will get soaked and you can reduce the amount of Wolfgang you use. Afterward, you'll probably want to wipe everything down with a clean, dry cloth to remove any excess (but I never do, lol). My 2018 car has a black finish which I don't like because it tarnishes over time and looks horrible. However, this material will make your car's black trim look brand new. I used it every 2 months for the first year but then I didn't apply it for over a year but when I finally did the black finish was fully restored. After 1 month the black finish is still clean, dark (ie not dry or grey) and looks great. I've also used it on the dash and vinyl plastic trim and it looks great. I was a bit worried that the car would smell like exhaust fumes, but that wasn't the case at all. I bought a second bottle in case there was a disruption in the supply chain and Wolfgang was no longer available.
