Yes and no. Thin down the paint, brush liberally over the model and allow the wash to get into the nooks and crannies, then sop up the excess. There are numerous videos on YT that will give you an idea of how to do it. Ensure you use the correct technique. Applying wash to a tank model to give it weathering might not get the right look. You want something that looks like a shiny plaque that has a cast metal effect or oxidation.
Dry brushing is using a small amount of paint, with the brush dry and lightly going over the edges.
