how do u weather desert aircraft

lucky for you I logged on, I work on Aircraft in a Desert, so hopefully i can help.
I assume we're talking North Africa here. So, desert, incredible heat, sandstorms, etc. The paint would be faded, and, in places, blasted off by sand, mostly on leading edges, though fabric covered control surfaces would tend to be ratty & even more faded than metal surfaces. Also don't forget to weather markings, roundels etc, they were painted on after all.
Your best bet may be to prime the kit, then paint in aluminium/silver ( I use acrylic car spray) Don't rub this coat down!
Apply the camouflage colours, having lightened them with at least ten per cent white. leave to dry & then very lightly sand (micromesh if you have it) until the silver starts to show through in places.
Apply a gloss coat, apply your wash for panel lines, then lightly rub down again to bed in & fade the markings. Use pastels to blend in & fade things a bit more and apply a dull coat to hold it all together.
et voila! a well used Desert P-40 or whatever.
I hope this is of help to you,
Pete

I'll only add this: You may want to check out the "Salt technique" (search in the techniques or weathering forums) for paint chips. And don't forget the leading edge of the prop blades.

i apprecate the help but im new at htis whetherin gthing so could u put it steps as if u were explaing it to a moron and by the way is dry brushing a good idea

One technique that I'm still experimenting with, is to airbrush a thin white (or white/yellow/brown) wash to help show faiding.

Sandblast it.

Bigshot, your best bet is to spend a couple of hours on the techniques part of the forum, going through some of the old stuff on weathering, dry brushing and painting tips. you'll learn an amazing amount, probably too much for a beginner, so print out some of it & look at it later.
Sorry I can't be of more help but my email/web time is limited & the server is very slow, so I have to get on line when I can. To explain it all properly would take hours from here.
All the best

It's early morning here & I managed to get back on line okay, so...
Quick guide to drybrushing.
I think your colours will be stone & earth, so paint the 'plane in those & let it all dry overnight.
Take one of those colours, put a small amount in a container, add about 1/3 white, then 1/2 again of thinner.
take a large(ish) brush, just dip the end in the mix, lightly brush it onto a rag until there is almost no paint left on it. Now apply it lightly on that colour on the model, painting from front to back. You will see that the paint only sticks to the high points (rivets,joints etc)
Let it dry, then do the same with the other colour, and on the underside too.
If it seems okay to you then fine, if not then do it again with even more white in the colours.
When you are happy with it, stop, don't take it too far. You are then ready to decal, though this method can be used after that too.
Practice on an old model first ,if you can. The idea is to fool the eye in a subtle way and add depth to the reflection of light from your model without adding too much depth to the paint .

well it really depends on the Aircraft Maintainers, here's a very good example, I'm in the 442 FW deployed to Iraq we wash our A-10's about once every 2 weeks to keep the grime down, but our sister unit the 23 FW(Flying Tigers) don't wash their Aircraft or do it very poorly, because if you see photo of our planes we really don't have any heavy weathering, but as for the other unit you see it alot, also if you are going to do a Warbird then alot of grime is in the areas where fluids are persent like on top of the engine servicing areas, around the greased areas on the landing gear and flight control hinges, and the skuff marks around the walk areas and on the leading edges, also the darker colors fade quicker then the lighter colors so this maybe how you want to start the project, there are many different ways to do exhaust stains & gun burn stains you could try to use an gum eraser to get the effect on bleaching the paint then dry brush the blackened soot where the carbon deposits would lay on the trail, it's best to try all type of weathering on an old model before you try to apply it on you show subject if you have any questions you could E-mail at 72cuda@gimail.af.mil for more answers

im talkin about a bf-110 anf a hawker hurricane what is sandblasting

sand blasting is a process used to remove paint from metal, how to simulate this is dip a #3 brush in silver paint and wipe the paint off with an old rag and then brush stroke the area that's to be "sandblasted" like the leading edge of the planes wings and tail or even the props and spinners, also you might want to do a different shaded panel effect(in the field the maintainers did meatball repairs like scab patchs on the aircraft skin to cover bullet holes) like a darker shade of tans or browns to simulate field repairs or to cover an old paint chip, if you can find a color pix of the subject you are doing like your Bf-110 and get an idea of the weathering areas and type of paint damages I think you can simulate this on you next project, the more you do then the easier it'll become and the more different types of weathering styles you'll try

awsome
