Sealing PLA & oil-based art supplies?
I have worked with PLA and paints before. I use mainly acryl-based paints as well as spray lacquers.
Sealent is not necessary.
While a sealant is not necessary, you might prefer to use a spray on, smooth drying lacquer to get a smooth surface. PLA does not &quot;soak in&quot; paints or colors like resins.
