First of all you need to convert the model to a UV map, which, if you don't know, is the model with certain edges cut so that it lays flat. Output the UV map to an image file, like .JPG or.BMP. Open it with a free image editing program such as GIMP or Paint.NET. All it is is a bunch of lines showing the edges. Paint your ship to resemble a Volkswagen Westfalia from the 60s. Import the texture back onto your model. I'm no expert (I'm learning MAX as I type) but I'm pretty sure that that's the gist of it.
EDIT: And from what I hear, Wings 3D can't UV map.
