Weathering paint ^^The first thing you're gonna want to so is get your colors applied. It's not always necessary to weather all your colors. in this project, I'm only weathering the red stripes. If you have multiple colors and want to only weather one of them, simply lay up your primary color then clear coat it. (You can also choose to have your ground coat as a metal color and weather through a topcoat to reveal the steel underneath.) Once that's finished, sand that down and apply your secondary color. ^^Also doin the wings up. Be sure to spray in light coats to avoid any bleeding through under the tape. ^^Shown beside the project is a piece of 3M scotchbrite. You can choose to use a red piece for a coarser look (320 scratch equivalent) or go with the grey (1000 scratch equivalent) I'm using the red here. ^^Gently rub the scotchbrite pad over the painted surface from front to back in a complete stroke. (Never go from back to front) It's best to focus most of the scratch on any high spots or high crowns in the panels as this is where the paint would be most likely to wear out. ^^The wing too get rubbed down from front to back focusing on high spots and blunt edges where the paint is most likely to be worn away. ^^With the apint worn, apply all decals you intend to "dirty up" ^^Now clearcoat over the project so we can move on to the next step. You want a layer of clear between the two so should you make a mistake on the next part, you won't have to start over from the beginning. (Do not get too heavy with the clear or the features in the plastic will fade as the project progresses). ^^Sand down the clear with 1000 scotchbrite for the next step.
