Hi everyone, can anybody advise what to use to use to dull down oil paints that have dried with a shine. I have heard reference in previous threads to dullcote and was wondering if this was a specific brand or just a generic term. I paint with artist oils over humbrol enamel base colours. I currently have some humbrol Matt cote and some life colour acrylic Matt cote and was wondering if either of these would work ( would the enamel based humbrol react with the oil paint and start lifting it or would the acrylic be able to key to the oil finish?). I would also like to know if I should apply the Matt cote once I have completed the figure or would I be able to do the affected area without it causing me issues when I come to paint the unaffected areas. Any advice would be greatly appreciated.
