I've tried 2 layers of 476s, no noticeable change in durability though.

Also tried applying 476s and layered 845 above it after a day, again, no noticeable change in durability.

BTW, our car is 24/7 parked outside, rain or shine. That's why it gets contaminated easily with 'libag' or dusts formed from rain and baked in the sun.

Even on a fresh coat of 476s it is still hard to remove with just a regular wash.
So a single coat would suffice? what do you recommend sir? 476s or 845?
