I'm new to this forum and I know this is an old thread but I was interested in the reference to GrainIt Technologies method in a post above.
I do faux wood graining using GrainIt Tech method and materials. The Chrysler in the photo WAS a 47 Windsor that a client turned into a Town and Country replica. The frames are real wood attached to the body and the paneling I did in the proper Mahogany grain. It was done for a vineyard and resort owner to take guests around and for branding.
