MCW finishes recommends thinning our enamel paint at about three parts paint 1 part thinner for our flat colors,and 3 parts paint 2 parts thinner, up to 1-part paint and 1 part thinner with our gloss colors. Our Primer needsto be thinned 1 part primer to 2 parts thinner. This will vary depending on your airbrush and sprayingconditions. We recommend using our enamel reducer or lacquer thinner. Do not use mineral spirits.In our trials, we sprayed the paint at about 25-30 psi. Depending on airbrush and conditions you may want toadjust your pressure up or down.We recommend spraying it a lower pressure for fine details also for fine details you may want to some morereducer.Our Enamel Clear (1017E) is a crystal-clear enamel. It will dry on its own but stays soft. We recommend usingour 1017EH Clear Hardener. The mix ratio is 2 parts clear to 1 part hardener and thin as desired.You can add our Enamel Hardener (1003E)to the paint which will fully cure it in eight hours at 70 degrees F.This will make the paint less likely to be reactivated with additional coats of enamels. If you want to add thehardener, the ratio is 8 parts paint, 1-part hardener, and 1-2 parts thinner. We recommend that you do not addhardener to any paint that you do not plan on using right away. If you are using a color cup, use a pipette tomix using the above ratio.We recommend using a good primer like our MCW line of primers to help adhesion and to help avoid pooling orpulling from high and low spots. Once dry the paint can be wet sanded and buffed to a high shine and one of yourfavorite clears can be applied. We recommend thinning our primer 1 part primer to 2 parts thinner.We are always striving to improve our products, so please contact us with any concerns. We recommend that youpractice before using our paints as in most cases they tend to shoot a lot different than other paints you mayhave used.
