Here’s another one for ya!!!
On weathering…First, I’d highly recommend spraying with a rattlecan, but this method will also work with a brush painted model. Once your model is painted, lay down some black pastel chalk along the panel lines(charcoal sticks from the arts-n-crafts section work fine too. I use a piece of sandpaper as a palette to grind the chalk down into a powder). I use a farely small, flat/wide brush, dip in chalk, run it along the panel. (doesn’t take much!)
This is what it looks like at this point…
Next, take your base color (same color you originally painted with), and dry(ish)brush over the pastels, getting them mixed in with the paint. Keep it farely localized around the panel lines, with a few random streaks in the direction of airflow.
Here’s a before/after of this step…
…and another after…
It looks like he!!, I know…don’t be scared!
Once you’ve finished this step, all the way around, use your base color again, but lighten it just a touch (with greens, I lighten with a couple drops of light tan…go easy on it!). Now, using the slightly lighter color, drybrush again, randomly, all over (if that makes any sense!!!). I try to keep this drybrushing step more within the center portion of the panels.
Now, it looks like this…
The next step is to spray a gloss coat for your decals, followed by a flat coat to seal the deal.
I dabbed on a little more chalks along heavy traffic areas, as well as making a few streaks, after the final flat coat.
The finished product…
