Shiny figure?

Posted in Custom Workstation

Hello all. I'm new to customizing and trying to learn. I'm working on a marvel legends figure where I'm doing a simple repaint using model masters acryl paint. After 24 hours I checked the area that I'm working on and it's very shiny. I want something flat looking like the figures normally are. I've read that using dullcote might be what I want to get rid of that shiny look. They have the spray can and the bottle of dullcote. Is it okay to just get the bottle of dullcote and paint it on with a brush? I've also read that dullcote can "melt" the paint or distort it. Is there a certain technique to use with it? Any advice much appreciated, thanks!
