Can you cover up tan lines?

Depending on the severity of the tan lines, getting an SunnaTan can definitely help blend them. Simply choose a colour that is similar to your client’s existing tan. Tan the body 1-2 times like you normally would. Then apply several light extra coats on the white areas along the tan lines, being careful not to darken outside the lines, and using air on your gun to dry these areas in between coats. Essentially you’re applying 4-8 coats on the white areas and 1-2 coats on the tanned part of the body.
