I've oil washed probably 100 models (all of them dullcoat over enamel or otherwise Tamiya acrylic  flat paint). You're asking for trouble washing a gloss surface.

I doubt it has anything to do with the thinner. I use odorless thinner from Home Depot. Its just my opinion that it is a little less caustic to the paint ( if you've dullcoated over enamels for instance) than using regular.

If you're using acrylic is won't matter which you use.

 

My advice is to pick up some really cheap throw away models and practice on them.  Nothing beats practice and there is a learning curve to getting a realistic look from an oil wash without screwing it up..... It does work well once you master it.

I prefer to apply it on gloss surfaces so the wash can be removed/ blended later on. Also i get really bad tide/ water marks on matte surfaces.

 

Karl- Can you post a picture of the mineral spirits you use?

Try using just regular mineral spirits. I use that with 502 oils and they work wonderfully.

I agree with what Bill has said. I do remember as a younger modeller using Rowney oils for washes and the thinner I made the wash the more crap started to show up and this was because some of their shades of oil paint had pigments that did just not dissolve or thin out properly.

Now for another point, have you tried putting your wash down on to a matt surface? It's just a thought. Its just a personal thing with me that I find that a wash will go down beter on a mat surface. Try it on something from the spares box first.

 

Hope this helps,

 

Terry.

It sounds like you may have some contamination happening with your brush, the thinner, or the paint that is causing the paint pigment to not properly "thin" and instead is only being suspended in the thinner and, once dry, it clumps together as the thinner evaporates. I'd start with the brush first and make sure it's clean and not recently used for any other projects/medium types that might be causing an issue. If that's not the cause, then you may have a bad tube of paint.

I tried applying a wash of 502 oils with 502 orderless turpentine and the results are less than satisfactory.  go on well but when they dry the color is not nice, even, and smooth but rather spottly and pixilated, like the pigments in the paint are seperated.  Im applying the wash on a gloss surface and even a semi-gloss surface with similar results.

Any idea why this is happening? anyone else have this problem? Ive never read of anyone else having a similar issue.
