I had very bad oxidation on the fenders flares of my truck. I had tried other products and could not remove it. I was ready to get those parts repainted, when Jonathan told me he had products that could remove it. I didn’t believe him but was willing to try. Sure enough he removed the oxidation. He recommended sealing the truck afterwards which I did then and there. My girlfriend said the truck looked so good, she wanted me to detail her car using Griots products. Thank you Jonathan for the introduction to High Quality car care products, and a multi step process. Its a huge difference from the “stuff” you get at the automotive stores.
