have used your 845 wax for years and have found nothing better.I also used it on my fisher plow that was 6 years old and still looked like new.it would stay on face of plow for a full season of plowing,great stuff.I had told my friend about the 845 wax and he found it worked good on his boat,made it clean up much easer.when I ordered the 476S wax to put on my snow blower he ordered the wax for his boat that is still in storage,will let you know how it works
