Bought an airbrush and am currently weathering my vehicles.(WWll) with Tamiya acrylics.
Looking at all the U-Tube videos on the subject,( mainly weathering electric trains):loony one video said you would have to seal the weathering as will wear off with handling.
It says that acrylic paint will come off on plastic.
Is this true?:think
Is there an acrylic dull coat sealer?

Well, any paint will come off sooner or later if not protected. The best thing to do is to first seal with a gloss acrylic varnish for strength (2-3 layers are probably good enough), and then to use a dull coat on top of that.
