Within the last two years, I thought I saw an article in Model Railroader on weathering freight cars with water colors (or maybe weathering frieght cars with water soluble techniques?) and I can’t remember which one it was. I keep my past issues of MRR so can anyone tell me which issue that was? It might have benn by Pelle Soeborg but I couldn’t say that for sure.
I don’t have the information you need about the article, sorry, but I do all my weathering with the dry-brush technique or with washes of different densities using plain old water-based acrylic craft paints available at artist supply stores, craft stores, and in the paints and crafts section at large box stores.
It works with a bit of persistence, courage, and practice. My first job was grossly overdone, but at least I saw results as I went along.

Watercolours work just fine, the one problem is the cost of a small tube of w/c paint is high, but they do go a long way, just don’t lick the brushes, some of the paints are dangerous, but they are modifying them.
I think the article you are thinking about is “Weather With Washes” by Mike Tylick, in the July 2008 Model Railroader, page 44. He uses watercolors (but other paints too such as poster paints!), very much thinned, and applied with a brush.
Originally there was an online extra supplement to the article showing more examples, but evidently that is no longer kept up probably due to age of the article.
