The weathering process started by fading top surfaces with a very light mist of white heavily thinned (actually it is more a layer of thinner with a single drop of white) on a salted model.


Salt was applied on the humid model (top surface only) and then left to dry for a couple of hours, then the white misted was sprayed



The salt bits should be fine and eventhough they may not be visible when deposited on the water, they will become much visible after the water evaporated



Once the paint was dry, the model was cleaned of it's salt with a brush and water.

This is very subtle and almost impossible to see on the camouflage, but the overall effect is very convincing, unless it is overdone or the salt bits are too coarse.



It is much more visible on the prop, Not surprisingly due to the black base colour. 

But that's exactly the effect I wanted to get.




Then more salt was applied on both top and undersufaces for the next weathering paint layer.

This time i'll concentrate on area where a black mist (thinner +a drop of black) is appropriate. Doors, walkways, engine stain areas and undersufaces





On the top surfaces, the dark weathering was convincing.





I went a bit overboard on the undersurfaces, salt was too coarse and paint layer was too dark. But a quick mist of base colour fixed that issue at later stages.



The model was then completely rinced with water to try to eliminate as much salt as possible.
The above weathering were done in quick succession to avoid the salt staying too long on the model. Not sure it would have any impact but I'm not quite taking chances with salt :)


Thanks for looking

The effect achieved on the underside looks brilliant, I've never tried this before but will have to give it a go on my 1/32 :) Hope you don't mind me tagging along and copying technique, it's excellent to see what is possible and take inspiration from it now I'm returning to the hobby.

Can't wait to see (and totally copy ideas from) more :)

Sure, that's the spirit :)


some more advices:


- you won't see the effect until you wash the salt. You will always tempted to do more and that will result in overdone effects.
Be moderate, even if you find it is not enough after salt removal do another run, it will be even better.


-  the white pass is very light and usually gives subtle effect, the black pass is very easily overdone,


- Keep the salt fine, Don't use coarse salt. if you grind it, it's even better but make sure you grind it to acceptable fineness, Don't let big chunks of salt on your model covering a too great surface. Apply salt where it matters. over large area I move the grinder on top, on specific areas I usually grind on a piece of paper and apply the salt with a finger pinch


- Don't use an hairdryer to remove the water or speed up the drying process, you may remove the salt too

Some apply water with a brush, I made a small bottle spray and mist the model from that spraycan

Wait till it is totally dry to start painting


- paint at very low pressure, put thinner in your airbrush, dip a brush in white paint and mix the cup. One dip is more than enough. No need to fill that cup fully. Same for black, dip once, mix, paint.


- toroughly wash your model when the paint is dry (no need to wait a day, 1h seems to be more than enough with acrylics, but it dépends on the paint you use obviously.


- if the effect is overdone, no big deal, spray the base colour again to tone it down. Work from inside the panel to the outside.
In the process above I heavily overdid the flaps, I painted Inside the ribs and came out with an even better effect to my eyes.



The salt applied to the iner flaps was too coarse. The result wasn't satisfactory after the black pass.

the combination of too coarse salt and painting a dark mist over a light colour destroyed the subtility I wanted. I had to repaint the flaps in grey. But by misting it overall and painting more Inside the ribs I could salvage the issue and get the effect I wanted.


Have fun and post your progress,

Oh, and work in a big box, it's a messy process :)

Working on some details now,


Flaps were completed and glued in place:







The flap actuator PE part goes through the wing into the small opening to that effect. A rod was added and MasterCasters provided a PE door for the panel.

As stated earlier in this WIP by GregV and kindly reminded by Captain Boogaloo, the oleo are too long and the model stands too high on it's main gear.

They are 7.8 mm whereas they should be 4.8mm in 1/24th. This was indeed compared with the 1/32 tamiya measurements.


So I cut the oleo clean but rather than simply shortening them by 3 mm, I bore a hole in the main gear and sanded 3mm of the oleo thinner so it could insert it into the main gear.

I figured this would give me more stability:


The area needing sanding is marked by the yellow tale



The lower part sanded and ready to be inserted 



The wheels 


One of the gear completed




The final result with shorter oleos.

More small details:


The exhaust were hollowed, painted in black, slighly drybrushed with dark aluminium, then washed with streaking rust effect and pigmented with conrete light grey






The end is very close ....

Hi Red woofer! I did perhaps forget to mention the Mk IX oleo legs should also have scissor links pointing forward? Sorry Olly!!! In fact, if we're being pedantic, the oleo covers should be more curved around the legs than the Mk 1a.  Courtesy of Spanner in the works productions!!


Blue Skies!

PS love the salty dog paint effects!!

Thanks DutchMan


Duncan, that scissor link has been in the back of my head Indeed. I even already sourced a few candidate in the stash part bin

thanks for the reminder :)

Forget about the curved oléo though :)
