Thank you for the picture, your car looks great. I built an aluminum dash panel like yours one time and "engine turned" it using Cratex sticks. When I finished, the engine turning looked O.K., but everything was very "dull". I checked around and found out after the fact that the aluminum should have been polished to a high lustre before it was engine turned. Of course, if you polish it after it has been engine turned, you polish away all of the engine turning. Oh well, this is how we learn.
