Mont Marte Premium Iridescent Varnish 240ml

A finishing varnish that does more than protect — this iridescent formula from Mont Marte adds a subtle colour-shifting shimmer to finished acrylic or mixed-media pieces as light hits them from different angles. Brush it on as a final topcoat once your painting has fully cured to seal the surface against dust and UV fading while layering in a soft pearlescent effect that reads differently depending on viewing angle and lighting. Works best over darker or saturated base colours, where the shimmer effect shows up most clearly.
