Basic Dirt Effects Weathering Set (Train Series) is a three-jar blister of AK's 35 ml weathering products for making multiple dirt effects on trains and wagons — AK's own summary — with ultra-realistic results. It mixes product lines: two jars are enamel effects, Rainmarks for rain-streaked dirt and Decay Effect for heavier, decayed grime, while the third, Asphalt Road Dirt, is one of AK's ultrafine modelling pigments, applied dry or mixed with pigment fixer or white spirit for wet work. That enamel-plus-pigment mix is the point of the set: streaked and layered dirt first, a dusty, ground-in finish on top. Set contains (3 × 35 ml): AK074 Rainmarks, AK675 Decay Effect and AK146 Asphalt Road Dirt (pigment) Two jars are enamel effects; the third is an ultrafine modelling pigment — AK's instruction is to apply its pigments dry, or "Mix them with Pigment Fixer or White Spirit to apply them wet." AK's summary: "Special set to make multiple dirt effects on trains and wagons. Create your effects easily to get ultra-realism." All three jars are stocked by us separately as singles
