:-) A very nice looking Corsair, Leon. You should be justifiably proud of this
A couple of things you might consider for your next Corsair/aircraft: Part of the flying surfaces, on a Corsair, are fabric covered. These areas would weather differently to the metal parts, I masked and sprayed them a lighter hue but dry-brushing might give a good rendition of this.
To replicate deposits from the engine, or other areas of the airframe, apply minute dabs of Warm grey or Davey Grey, artists oil paint (they have a brownish hue) then "pull back" using a finger, cloth or cotton swab. Control it but don't make it look contrived.
Just a few paint chips, particularly around hatches that are always being opened, such as for engine access, gun/ammo and re-fueling. I use a silver pencil for this, after the matt coat. Fuel spilliage would always be present, I use highly thinned oil paint for this.
For tyres I paint with Xtracolor tyre black (very good) RLM 66 works well too. Black doesn't look right. Dry brush with earth colours. Tyres aren't actually matt, so a little sheen is OK. This will always be exagerated if using a flash when photographing.
You have done well to drill through the antenna post, but to manage this necessitated drilling to low down. To get the wire on the top of the post I simply pull it across the top and apply CA. When dry cut off the surplus with a sharp knife. I use a heated pin to put the tension in the wire. I did drill through the fin post though, this provides the anchour.
I think the main thing, though, to get the most realism, IMHO, is to apply the wash over the decals. Or in other words apply the decals, apply a protective coat (I use Klear [Future]) then weather. You may have done this but it isn't showing in the pics.
You may be able to see evidence of these things in my article on the Corsair
Pacific Corsair In any event, Leon, you have a Corsair to be proud of. It took me a lot longer to get as good as you :-) I blame the internet
Lets see more of your work. What are you working on now?
