Please help me guys as i love my bike very much and seeing a scratches on my bike is very annoying and disturbing....

Depending upon type of scratch, they can be either treated with such simple pen but they are not that much effective and works on very thin scratches, other way is simply visit a good dent remover in your area and he can suggest best to you.

Though, my friend once had similar stuff with his new pulsar bike, he went to service center and for few hundred rupee , got replaced his fuel tank completely. But he used other way and I guess he knew some insurance guy !
