I never use satin on my babies. It still has a shine to it, albeit low shine. I use a matte sealer if needed but just on the shiny areas. Be sure not to thin it with anything as it defeats the purpose of using it. Some causes of shiny babies... baking too hot, too long, or using a stripper too hard and rubbing the paint off. There are other reasons that you can use the search feature to find those threads. Hope this is ove help hun!
