Koch Chemie Finish Spray Exterior Reviews

This stuff is absolutely magic in a bottle. A must have for anyone with a darker vehicle. I've used it as a drying aid as well and works great and adds a super smooth finish to the paint and a jump in gloss

Yes again and again. I saw this product being talked about on the "Forensic Detail" YouTube channel and thought I'll give it a try. One of the best investment in a car detailing product I've made in a long time. It works as advertised. I had washed my car about a week or so ago when I got this product. So I washed it again this time using rinseless wash product. But rather then finishing that off with my usual drying agent, I used Fse and was I surprised with the results. It took old wash marks off along with recent water spotting making my car look freshly polished. I plan to use this product every three to six months to give it the fresh just polished look with stripping it of the coating on it.
