I was looking at properautocare.com (classic motoring accessories) and while they feel FMJ is the best sealant made, they do not recommend putting a carnuba topper on it. They said they tried Souvern and P21S and both dulled the finish; instead they suggested one should simply layer FMJ. Has anyone else had this experience? Though I've probably done 30 or 40 cars with FMJ, only twice have I put a carnuba on top (P21S) (people rarely want to pay for the extra time); I personally don't remember the P21S "dulling" the look of FMJ.
Any experience with FMJ welcome to chyme in.
