well in reply to the liquitex medium gloss and varnish stuffs over here in the uk, success, works like a dream, cheap and is available from several sources
I use the liquitex gloss varnish which has an orange label. you can buy a pot of it 118ml for £5 and it goes a pretty long wayhey esdain
was this the liquitex that you got
Just so I understand, when I paint the latex, you just paint it first with your colors, and then seal it with Permawet/Plastidip/alternative?
Or does each coat of paint have to be sealed with it?
