Wilder Product's Nitroline series' Light Brown Dirt Effect, item NL 25, is a light brown weathering product intended for speedily reproducing dirt.

Formed in 2011, Wilder Products produces effective finishing products and accessories for constructing, painting and weathering all types of scale replicas and dioramas. Mr. Wilder is well known across the modeling community for his elaborately weathered models, numerous 'How-To' demonstrative features, and collaboration with other well known vendors.

Recently the Airbrush Company Ltd sent a selection of products by Wilder Products for review. This review of the NitroLine paint Light Brown Dirt Effect will demonstrate how the product can enhance a model.

According to the Wilder website, NitroLine washes are:
    Enamel based products for quickly and easily applying various weathering effects onto all types of models and dioramas. NitroLine products can be used straight from the bottle or thinned using enamel thinner. Works best over acrylic finishes. Thoroughly mix and shake the bottle prior to use for best results.


    If done properly earth tones and effects when used with other weathering techniques can give you a very authentic looking replica that you will enjoy looking at on your shelf time and time again. There are different ways that you can apply NitroLine earth tones. They can be brushed on straight from the bottle or thinned using enamel thinner.

NitroLine Light Brown Dirt Effect
This paint is formulated to create a dirty surface. It is contained in an eye-catching unique bottle, more like an artists' ink jar, a necked square body plastic bottle. The attractive label adds to the aesthetics, although text on the side is so small that I can not read it without magnification.

Inside is a solvent-based liquid and a thin layer of pigment. The pigment is robust.

Having used these products I concur with Wilder's emphasis to thoroughly mix, or shake, NitroLine products prior to use to ensure that the pigments are completely mixed for the effect to work to its fullest potential.

Opening the bottle releases a mild terpenic odor, less intense than Model Master enamels, and less than the mineral spirits I use to clean my brushes.

Since Light Brown Dirt Effect is for any finish, I tested it on an olive Tiger tank. There is no reason that it can not enhance any railroad subject as it certainly looks like the color I saw underneath a caboose one summer.

I loaded a stiff bristle brush with the paint and flicked it across the surface. This paint is thin so it will quickly pool, yet it is very opaque! While it dried I brushed against it, causing streaking and irregular patterns. Please see the photographs to judge the effectiveness; the paint was applied and dried in about 20 minutes.

Unlike other Wilder Nitroline paints, it did not leave any shine.

Results and conclusion
Light Brown Dirt simulates a general gray-brown filth. It will grunge up any railroad item, simulate ground cover, or dirty up any vehicle.

The product is easy to use. It was easy to clean from the brush with mineral spirits. The odor of the solvents did not give me a headache. It dried with mild sheen.

Bottle design is nice although I wonder if modelers, at first, will be dubious about the uncommon square bottom? Yet modelers who enjoy a product will always find room for it.

Modelers striving to create a smutty effect and color modulating plus washes should appreciate this product. I have no complaint about this product and thus feel comfortable recommending it.
