Yes, the type of plastic/paint combination can have an affect but, also the paint/paint combination can affect the finish. That is for me the reason I choose to use the acrylics, they also have a much faster cure time. Acrylics at least from Badger are dry in 15 minutes. I do wait over-nite before masking and applying the next color, and if you want to see the collection of colors available you can look at their website. They also have a large selection of airbrushes and i can attest to their being excellent with their service if you need a part for an airbrush.
See their Modelflex Railroad colors, the drop down menu is under SHOP on the website
