Based on the texture found in the game files, I decided to recreate the green Molotov label

Replace in:
...\update\pc\models\cdimages
weapons.img 
w_molotov.wtd    texture named "ec_beer_brands_vkaec_beer_brands_vk1"

or

...\pc\models\cdimages
weapons.img 
w_molotov.wtd    texture named "ec_beer_brands_vkaec_beer_brands_vk1"


choose one of two texture one of tchem is translucent too much in my opinion.
