well i detail cars for a small car lot,as well as other folks. last yr,the car lot guy said some folks didnt like the gloss,from using meguiars #40.so o chainged products for him,to something that doesnt leave much shine,presta vinyl and leather cleaner. now,some customers dont like the shine of this stuff.so i went back to # 40. no one has complained yet. hope i dont have to change again.it costs too much.
