Tamiya's Liquid Surface Primer is perfect for smoothing over small scratches, holes, and gaps, and can be easily applied with a modeling brush. Furthermore, it can be thinned using separately available Tamiya Lacquer Thinner and applied with an airbrush, making this a very versatile tool for craft and hobby use. Comes in a 40 ml glass bottle.
good product, good for using with cheaper paints, and covering 3d prints
love the primer good for covering 3d prints and I like to use it with cheaper acrylic paints (apple barrel. I use tamyia paint by their self since i see no need if they stick well to the model. i would use a synthetic hair brush dedicated to the primmer i find that it doesn't come out of the bushes without removing the hairs.
