So l spent a lot of time on the interior of my car yesterday, glass cleaning,switches,leather etc etc but also washed it...prewash, tar removal and korrosol along the sides of the car...then applied some Wet coat....l also washed the mrs car...prewash korrosol...but also applied korrosol on the bonnet of her car to try and remove bug scarring..anyways after all of that l applied wet coat to her car,after a towel dry l still noticed some bug scars remained,so l thought detail spray to finish it off and remove the bug scarring, it did...used the Menzerna endless shine,very grabby..indeed but left a very high gloss finish..for a detailing spray that is...but no where near the likes of fusion wax...so it rained late evening.....WTF...Dreadful beading from this product and l mean almost non existent...l thought surely a bottle from a bad batch...even worse l applied endless shine to my entire car....flat as a pancake...guff
