Hi once again Dejan87,
You seem reluctant to take the advice we are offering you, it is a very simple fix...Take it to a reputable smash repairer, he will do a colour match for you, and spray the chain-case for you...apply the new decals you can get from willing worker (Grant) and the machine will be as good as new...no fuss or worries...and most importantly no rust!
cheers
