Various reasons for wearing gloves when building models here are some examples 1. keeps away the oil on your fingers leaving finger prints on parts especially windows 2. give you more grip when picking up screws and other small parts. 3. keeps your hands and fingers clean when using oil or grease. some people have skin conditions like Eczema which can be painful. Gloves prevent foreign objects like dirt, dust, oil and grease away from your hands... hopes this helps with your question.
