General How much paint is neccessary to cover mirrors and door handles?

[Ryder23]

I'm going to colour code my wingmirrors and door hands, 4 them as it's a 5dr!
The paint comes in 400ml cans, and i was wondering whether 1 will be enough to cover all handles and mirrors, or should i get 2 to be on the safe side?
The same goes with the primer.

Cheers

p.s, anyone got any reccomendations of where to buy the paint?

I did my door handles, bought a 300ml can, and still had bit left, and mines 5 door aswell.

Mirrors, i guess 2 more cans of 300ml

I just got mine from halfords tbh
