Hi, Duygu. You need to give us something to work with. Barrel or rack plating, acid or alkali, do you use auxiliary anodes, is the thin area within a hole? Let us at least picture the problem and then we may be able to suggest whether coverage is possible or if you need to look at another way of avoiding rust.
