So looks like acrylic with a additive to hold the dry time open. If im correct, what do you use to extend it, and how much extra time, roughly, does it give you, especially outside? Great work btw.
nothing to extend the drying time, i just try to keep a layer of water over top by using the spray bottle. The additive i squeezed out over the paint was Liquitex Matte Medium - this is more to extend the paint and alter the sheen rather than extend drying time. Thanks for watching!
