Polyurethane Mix Additive

Polyurethane Mix Additive helps model builders get more from their paint when it is time for a clean, controlled airbrush finish. By improving paint flow, this additive makes it easier to apply smooth, even coats that bring out the detail in your model rocket or scale project.

Better Flow for Airbrushing

Sometimes paint can be too thick to spray easily through an airbrush. Polyurethane Mix Additive helps improve flow, allowing paint to move more consistently through the airbrush for better coverage and a cleaner spray pattern.

Designed for Paint, Not Primers

This additive is made to be used with paint only and should not be added to primers. When mixed properly with compatible paint, it helps support a smoother application and a more refined final surface.

Smooth Eggshell Finish

For builders who care about the final look, Polyurethane Mix Additive helps create a smooth, light eggshell finish that feels polished without looking overly glossy. It is a smart addition to your finishing supplies when you want your rocket or model to look as good on display as it does on launch day.
