Recently I experimented with a new wash technique. I've used enamels and oil paints mixed into mineral spirits. Enamels must be removed with more mineral spirits - which makes them resiliant and durable, but not freindly.
Oils may be removed with a cloth or cotton swab. But they still require mineral spirits or turpentine to dissolve, and not all oils paints are fine-grained pigments.
I finally tried using pastels. Many thanks to Zombe for his earlier reports, which got me thinking. Simply lightly shave some dust from a chalk pastel into a container - a small cup or mixing well. Then add a bit of water, and a surfactant of some sort. I used Floquil's flow aid, simply a non-sudsing detergent. A rinse aid for the dishwasher reportedly works well, too.
Then I applied the wash in the traditional manner, allowing it to flow into panel lines. It worked great, and dried quickly. Small overapplications were easily removed via cotton swab.
I mixed various colors of pastels until I got the hue I was looking for. This let me make a grimy version of the base coat for realism.

I love working with pastels. It's has got to be the easiest way I have ever ran arcoss for weathering.
Get a soft fluffy brush, called a mop. Dab it in some white pastel dush, tap the worst off in your hand and run the brush lightly across the top of you model to get very soft hilights or go harder to get faded paint or wind blasted paint.

A guy in my club is a big fan of using pastels for weathering. The thing he tells me is that what you buy in the craft stores are not too great. The pastel chaulks are to be of top quality (in my book meaning pricey). Very cream like in texture. Very fine dust comes off of the stick when you scrape it off the color stick.
I guess in the short end of it is that you buy cheap pastels, you get what you buy.

Located said surfactant and mixed the concoction and applied it to an Ertl Tyderium kit. It makes a great "rebel scum" grime coat. I like that it dries fast, you can work it around a little like a glaze. Wish I'd have had it when I built 4 Ertl tie fighters last month, because the turpenoid I used in an oil wash bled over into the black area of the "solar" panels and stained them causing a lot more work. Another trick for the bag of tricks. Thanks TER-OR!

Glad to help.
But remember, very smooth glossy surface for panel lines. I just had to repair some bad lines on my Ventura. The surface isn't very good, so there was lots of pigment I couln't remove with the wet Q-tip.
I've got more to learn about this stuff!
It's easy to blend colors, though.

Consistency ???
What kind of consisitency should this wash be? Should it be like 'dirty-water' or should it be thicker like paint?
Thanks
Thanks

When I first attempted this experiment, I made the washes like "dirty water" as you put it. The reason being is you want the wash to flow into fine areas.
That's why you add just a drop or two of laundry detergent to the mixture. It drops the surface tension and makes the wash flow better.
When you mix the stuff, add the pastel powder to a well in a mixing palette, then add just a bit of water. Mix thoroughly until all the pastel is wet, and the mixture is a little thick. Also, before you add the water, you might like to "grind" the dust a little to help it get nice and suspended - I use a piantbrush.
After you've made your initial soup, and the pastel is throughly distributed through the water, add more water, stir some more, and then add a drop or two of laundry detergent.
Does this help?

That is a perfect explanation, thanks Zombe.
What brand of pastel chalk do you use and is there an online source for it? I went to a couple art supply stores and all they carry are the oil-based pastels and I'm pretty sure these won't work for this technique.

You don't want the oil pastels. They're oil paint in a semi-solid media.
I've seen pastels at art shops, but I can't remember if I have seen them at the big chain shops like Michaels.

Re: Thanks !!
I have a full artist's set of "Alphacolor" brand pastels. I think they were made by a company called WC. But, it's hard to say since this set is about 25 or 30 years old. Seriously. They last forever.dkeets wrote:That is a perfect explanation, thanks Zombe.

But yes, you, Ter, and kyl are right. Don't use the oil pastels. They won't mix well.
In my earlier post, I meant to say I grind with a paintbrush handle, not just the brush itself. I do this in the palette like an old-fashioned mortar and pestil. Make sense?
I was just at Michaels today, and I saw some of the chalk pastels, but I didn't pay attention to the price, no pun intended.
But, when you get it right, and it's easy, you'll never go back to anything petroleum-based again.

I swear by pastels.
I use Grumbacher soft pastel chalks. My set is pretty old...over 20 years, but they probably have 50 or 60 years left at this point!
I've simulated panel line weathering by dry brushing on whatever custom color I've mixed as described above, except without the water or soap ( if you go this route you MUST clear coat immediately as the weathering is delicate ) using post-it notes with the sticky side cut to the size and shape of the mask I want and then removing the mask.
It's a simple but effective technique for very subtle weathering on subjects like smooth starship hulls, etc. which have no molded-in panel lines.

I have some clips of Ter_or sifi58 doing a pastel demo if anyone's <a href="http://kc6sye.no-ip.com/techmages_3_13_04.html" target="_blank">interested</a>. . .

Re: Thanks !!
Zombe, have you (or for that matter anyone) used this technique for doing windows and such? I ask because if I can eliminate using oils all together , I will!Lt.

Question: I apply a coat of Future, and I apply a wash to the model. My wash is done, so I apply a coat of clear flat to seal it in. Now, I want to weather with pastels. Will the pastel chalk show off any fingerprints on the model? How do I remove the fingerprints? After I'm done weathering with the pastels, am I done? Or do I need to seal the pastels with more flat clear? Won't the pastel chalk fall off over time? Does the presence of the chalk make it almost impossible to dust off the model in the future?
"Dogs and cats, living together...MASS HYSTERIA!!!"
Some pastel's don't react well to being sealed. White, for instance, disapears under most sealers.nicholjm wrote:Question: I apply a coat of Future, and I apply a wash to the model.

I try to touch the model as little as possible after being weathered with pastels, but there are usually pick-up points you can use that have no pastels on them.

Ter_or says a light coat of flat to seal in the pastels, there is text in the link I had above, BTW I pulled the mpeg clips to save space.

Two excellent (AND FREE) videos describing post-shading. They also have a great pre-shading video.

The Tamiya powders also hold up well when sprayed with clear coat. They don't disappear like plain chalks do. The sponge applicator the sets come with works alright, but you can find small pointy sponges with handles at arts and craft stores (got mine at Hobby Lobby). I also like to use the super-cheap Testor's paint brushes (the white plastic kind with the black nylon bristles); just trim the bristles to a short stump. Works great.
