i couldnt buy novus 3 as i ran out of allowance

goo-gone spray
novus 1
novus 2
For the extremely permanent black marks/ i just use a tiny bit of goo gone spray, because the black marks are extremely tough to get off using novus 2.
For the slightly black marks and tiny scratches i use novus 2.
after using both solutions i use novus 1 to polish the plastic.
i then air the armour for awhile before sotring them in my luggage.
hope this is a good technique to use. do u have any other methods? pls care to share and maybe we can learn from each other!
