we first recommended 845 since its the most user friendly of all 3 collinites, people who use collinites can sometimes have a really hard time removing them so 845 is basically the default recommendation when it comes to their waxes so first time users won't have a hard time, as for 476 and 915 they can both be a PITA to remove even for me and my BF who have applied these hundreds of times already but 915 and 476 are more durable than the 845 the difference between 915 and 476 is that 915 has at least 20% more carnauba than 476 providing a deeper gloss, 476 however has more polymers that protect making it more durable.
