I am looking at my stock of enamel paints and find that some colours that would be useful to mix together to get possibly the desired colour differ in finish. I have matts and glosses. My question is can you mix a matt with a gloss? If so, does it become a gloss, matt or maybe a satin finish?

I will probably go and buy what I need but not knowing the answer is killing me. I was given 20 or so humbrol tins of paint from my son if the brand helps in formulating your answer.
