I'm interested into doing OOAK doll repaints and etc, but here in Brazil you just can't find good sealants for this type of work, the best sealant for this type of work is a japanese one called Mr. Super Clear(MSC) but i just can't import this type of stuff. The sealant needs to be able to hold/protect acrylic paints, pastel and watercolor pencils, and have a dried layer surface that can be worked again onto with the same materials listed before.

Mr Super Clear is just a lacquer clear coat, given of their own formulation but still just lacquer clear coat.

So do you know of any Brazilian spray sealants/varnishes that fall into that category then? Sorry i don't know anything about this varnish and terminology stuff.
I dont know about Brazilian brands or what's available there but maybe if you look into products marketed to other hobbies like wargames and model trains you might be able to find something that works how you want. Also, as you're probably aware, spray finishes dont do so good in hot humid conditions, so maybe a brush-on might be a better choice, and easier to import.
