Ready to paint - right on Fred
Weathering is easy - once you know what you want it to look like. Here's a weathering exercise for you then. Paint your Corsair and a scrap piece of plastic (like a 4"x8" evergreen sheet) in it's base color. Then when you are ready to weather it, try what you are thinking on the test piece first. If it looks good, do it on the model. If not, make any adjustments and try again. Do this for everything - washes, drybrushing, adding pigments, pastels whatever! You will get this - trust meeeeeee (like there's words you want to hear me say - right )
If you don't want to do that, run to the hobby shop and grab a $10 Acadamy 1/72 Corsair and practice on it (I'm brutal I know )
