MTN Hardcore Spray Paint 400ml Himalayan Blue RV-13 is a high pressure and perfect covering spray paint. The Hardcore range of 142 shades encompasses a wide spectrum of intense colours whose gloss finish makes them more striking. The paint dries quickly and after 24-48 hours, depending on the number of coats applied and the atmospheric conditions, the film hardens completely, thus increasing its resistance. Montana Colors Hardcore RV13 - Himalayan Blue is a mid-greenish-blue hue.
