hi currently i have a two huge key marks on my drivers side door which take it back to the metal, which seriously pissed me off.

i have perchase halfords kit for my car which includes laquer primer and the metallic paint but that is at least a three day process
been looking up on ebay and found this item.
http://tinyurl.com/36kdw4gbasically a scratch remover pen, just wanted to know if anyone have used this as a tempory fix as i currently dont have time for a full
3 days of painting due to my job and studies.
any help would be brilliant.
