Mission Models 30ml (1oz) US Army Olive Drab FS 319 MMP-024 Mission Models acrylic line of paint is non-solvent based and odorless. We have invested hMission Modelss of time researching and developing this new line to meet Mission Models high standards and the ability to offer the best paints for scale modelers and graphic artists. Mission Models paints incorporate the finest ground and highest quality lightfast pigments. Mission Models Formula is triple pigmented and does not include any additional thinners or reducers which in time can cause a break down of the paint and diminish shelf life and quality.Because Mission Models paint is triple pigmented and ultra fine you will find that MMP offers superior and beautiful coverage utilizing thin coats from the airbrush. Due to the fact that Mission Models pigments are so fine spraying through airbrushes with .015 and .2 needles found on many airbrushes is not a problem as wilth so many other hobby paints.Mission Models paints are airbrush ready and can spray straight from the bottle with no issue and minimal tip dry. We do recommend adding one or two drops of Mission Models Polyurethane Intermix when spraying straight from the bottle for enhanced flow and slower drying time when atomizing from the airbrush tip.We have extensively tested in all conditions from winter cold to 105 degrees with 90% humidity with virtually no tip dry and no clogging of the airbrush. Although Mission Models paint is designed for airbrushing but also ideal for brush painting.Mission Models Paints will accept all manufactures clear coats with out conflict. Yet we recommend Mission Models own clears.Oil and enamel rendering , tinting and washes will pose no problems. We also offer Mission Models own Thinner which is technically a reducer. Mission Models acrylic Thinner/Reducer acts as two different products. It is Mission Models Thinner and Mission Models airbrush cleaner. Many other products on the market require a separate reducer, flow enhancer, thinner and AB cleaner. Not Mission Modelss. Simply add the thinner to Mission Models paint, mix to the recommended ratio os 20 to 30% to 1. ( 2 or 3 drops thinner to 10 drops paint) and Mission Models done.Although the paint performs flawlessly straight from the bottle thinning it down with Mission Models Thinner / Reducer brings out the best. Mission Models thinner is also Mission Models airbrush cleaner. It is NON ammonia based and will not strip the finish off Mission Models tools.Polyurethane Intermix In addition to Mission Models Thinner we also have Mission Models Acrylic Polyurethane Mix. The MMP poly mix is an automotive grade additive and an integral part of Mission Models system. Like the paint it is very easy to use. After thinning Mission Models paint with Mission Models thinner flip the cap on the poly with Mission Models thumb turn the bottle completely upside down ( creates a vacuum effect in the bottle) and squeeze out a few drops into the paint and mix. One or two drops is all you need.For best results we highly recommend stirring the Poly and Thinner in Mission Models mixing up. DO not shake. The poly additive is beneficial as it increases durability , sanding properties and further Leveling. You do not need to use the poly to make the paint work as intended but adding the poly to Mission Models reduced paint will give you increased and unbelievable museum quality results. Mission Models Polyurethane will slow the drying time so less is more. If you add too much Poly the paint will dry slower. Don’t worry it will dry it will just take longer. We prefer to add one or two drops of Polyurethane to the paint when spraying straight from the bottle. There is no need to add poly to Mission Models primer. Primers : Mission Models acrylic primers are also very easy to use. Thin using Mission Models thinner ONLY. No substitutes period. Mission Models primers need to be activated. Mixing in Mission Models thinner will instantly activate the primer. There are no tricks. Mission Models primer is acrylic and also non solvent based. Activating the primer will not turn it hot and will not damage any materials at all.The primer must be thinned for proper performance and leveling. Mix it like you would mix paint. 20 to 30 % ( 2 or 3 drops thinner to 10 drops paint ) You do not have to do any thing different. We do not recommend spraying straight from the bottle as the primer is thick so must be thinned. Mission Models airbrush can be rinsed with water and then final spray though though with MMP thinner. The Mission Models primer is dry to the touch in about 15min and drys super smooth and incredibly durable. No sanding required.
