Whats the difference between enamel and acrylic paints for plastic model kits?
For models you mean? Enamels are solvent based, acrylics are water based. Enamel paint dries tough as nails and gives complete coverage in just one or two coats and it has a very “solid” finish which is why it continues to be popular with vehicle model kit builders. Acrylics are much thinner; essentially they are slightly transparent (not fully opaque) so the coat underneath shows through a little. Acrylics are very delicate and you have to avoid touching the surface or it rubs off – a coat of varnish is needed to protect the finished model. The big advantage of acrylics is that being so thin they do not obscure fine detail (diluted they can be taken down almost to the consistency of water) and with patience and several layers you can build up a smooth finish. Acrylic also dries fast – just a few seconds is enough. Acrylics are the usual medium for miniatures: http://www.boathouseloopers.com/images/m…
