There are charcoal pencils in the art shop that are ideal for drawings. One can wipe off much charcoal before painting over it. Lead pencils have a tendency to show through. (In fact, the particles can migrate through the layers.) However, some artists, like Georges Braque, appreciated this, presumably because it, in some way, enhances the creative expression. Modern painters tend to like the imprint of the brush hairs, and the lines of the underlying drawing. They often allow the canvas to show through. It should be evident that it is handicraft and preferably look like it was done yesterday. Perfection is not to be sought. Making a sketch with thinned oil paint is fine, too. Many use acrylic paint for this purpose, although some say it's not recommendable.
