WEATHERED USING WEATHERING LIQUID & AIR BRUSH

This example shows how to weather a Roco 66231 wagon. I sprayed about 4 coats on this wagon and mostly used Light Grey, Moss Green and Mud Brown. If you would like to thin the liquid, just use water. You can get some strange effects by spraying very wet liquid (but it takes a while to dry).

If you are spraying using an airbrush please do it in a well ventilated space and wear a good quality face mask. If the spray is bouncing off the model, add some water to the weathering liquid and this will help.

Clean wagon - Un-weathered
Clean wagon - Un-weathered.	Spray weathering liquid onto model. I use a low pressure - about 10psi. Don't apply too much at one time, just very light coats. I sprayed a coat of Light Grey on the roof first, followed by a coat of Moss Green.	First coat - Light Grey. This seemed to work best on this wagon. As usual, I tested all the colours first before starting. I thought Mud Brown would work well, but it looked wrong.
Spraying with Light Grey. After spraying the first few coats, gently wipe some of the dye off the model then re-spray. The more times you spray the darker the effect gets - spraying a few times allows some of the dye to build up in the board joints and make them darker.	I wiped the dye off the roof using a dry, or very slightly damp tissue. After some experimentation I found this was the best way to get the effect of water stains on the sides of the roof. You can use a cotton bud if you wish. I did this with a dry tissue just after the spray had dried, but not fully hardened.	This is the roof after wiping with a tissue. I then added a few more light coats, one of Light Grey, then a top coat of Moss Green.
Re-spray again and wipe the dye off using a wet cotton bud. Leave the dye untouched where you want the weathering stain marks. Also, leave it on where you would like darker weathering, perhaps around the upper filler hatch, hand grips and along the bottom of the wagon.	Spraying yet again. I added a light spray of Moss Green over the side panels and some Mud Brown to darken certain areas. Light Grey and Moss Green look good together. Clean the airbrush in warm water.	Wipe off the dye again with a cotton bud. I sprayed the roof with Moss Green for the final time, then wiped it with a dry cotton bud just after the spray had dried, but not fully hardened. This blurs the edges of the spray, blending colours. You can also use a wet cotton bud, it's all about experimenting to get the best effect.
I stopped at this point. It's hard to know when to stop spraying, but recently I have tried to put on less dye, and the effect seems to be more subtle - I prefer it. You can see here how I sprayed extra Light Grey over certain areas to make them darker.	Finish item - for the moment. I choose not to seal my models. If you don't seal them, over time a small amount of the dye rubs off, but I think this tends to improve the weathered effect.
