Just watched another video about the matt varnish and they have complained about the same issue. But then they explained why that happened - because the coating was too thick. Probably the same applies to the satin varnish. If you apply very thin layer of it, you will get better results.
welp i just bought another can, my first can i used looks good but that said it's the only one i used and tought that's how satin looked like, from far they kinda look more matt to me but up close it do be more gloss, welp guess il just use this fresh can as otherwise rip money and maybe switch any good cheap alternatives? as i don't wanna be paying like 20 euros a can as hat's expensive q.q
