***** Moderator's Note As with any automotive refinishing project, proper surface preparation and the correct tools are an important part of success. Consult with an autobody specialist before attempting any large-surface restoration for the proper techniques and tools. ***** Every repainted louver I have seen didn't look good. I think the problem starts from painting over Armor-all with the 'fish eye' effect coming through. Another mistake I have seen is people using a gloss paint. Gloss paint makes imperfections show up all the more. Sanding before you start makes it worse. The better sanded areas are more gloss and look uneven. I think the only way to get a good paint job on a greasy louver is to totally sand everything down, use a textured primer to match the original texture and then cover it with a flat black top coat. Maybe you could remove the grease by spraying it down with a few cans of disc brake cleaner or engine degreaser. Instead of paint, maybe you could looking into finding a good oil based ink or dye that is weather proof. I used a laundry marker with great success to touch up small areas on my louvers. Maybe something like what is used in a laundry marker or a black leather dye would work. If your louver is already saturated with Armor-all, then maybe fight fire with fire and give it a good rub down with black shoe polish. Ha! Don't knock it. It just might beat painting it.
