Painting - Woodgrain faux finish

I need to paint a new decorative steel insulated entry door. The outside will be painted a solid color, but the inside needs to be woodgrain finish to match the paneling. How do I faux finish the door? I've done other types of finish, but not woodgrain. Also, what's the best type paint to use on a steel door? It will get a lot of evening sun exposure (in the south).

dewgirl, A 100% acrylic latex primer rated for exterior use can go on both sides of the new door. Outside use whatever good house paint you would like. On the graining, first I am no faux artist and at best the graining we do as painters is laughable compared to a real artists work. Everyone isn't looking for that $300 door with birds eye maple graining. What we do is blend metal doors into the rest of the room. If matching paneling get a color that is as close to the background as possible or a little lighter because it will deepen as you add grain. Get this in an eggshell or satin. We make some on site out of scrap paints and others we have color matched at a pro paint store. We use urathane or varnish with stain in it for two reasons. The main reason is that it is durable and will bond with no worries and second, that is what we have on hand. Many bases can be used for the graining like oil and waterbased glazes. Mix some stain with the base and do samples to get the mix and a feel for what is happening. When doing flat doors lay off from top to bottom and some wiggling will produce a grain effect. That is about the best you can do without graining tools which a nothing more than feathers, combs and other odd objects. If you have a panel door, do look at a wood example to see how the door is built because this is what defines the way the grain runs which is both ways. Lay your door off like it would be if you were staining one section of it at a time. You will be surprise how well a grained door can look if the colors are right and the grain runs the right way and starts and stops in the right places. Hope this helps some.....Mike
