Hi guys!

Do you know if there are some professional products or one effective way in order to cover / paint the scratches or the nake metal points in the old black bodies of the cameras.
My "new" Nikon F3 body has many scratches and many parts without paint...
how can I cover these cosmetic imperfections!!!...I don't like it at all.
If i use a normal black pen (like the pen to write on the plastic of the cd)...it's very ugle because the two blacks aren't similar...and with the time the balck of the pen disappears...lefting the scratches and metal of the body visible.please help me!
