Yes! Transfer Gel can be used as a varnish. However, make sure to use a proper varnish brush when applying Transfer Gel as a varnish. Transfer Gel as a varnish is thicker than Clear Finish and Clear Topcoat making brushstrokes more visible and harder to control. Transfer Gel has a semi-gloss – glossy finish when used as a varnish. For a more consistent, even, or matte sheen – we recommend using Clear Topcoat or Clear Finish.
