aluminum interior
here are a few of my old car that I did. The doors are copies of the original panels and the back was free handed. I did the back sill too but did not take pics.
I have a 24" electric bead roller and access to an 8 foot break. I recommend buying your aluminium with clear or white vinyl on both sides. It makes it easier to roll, so you dont scratch the metal.
Also use cardboard templates for layout. When you draw out your bead lines make sure it will pass through the bead roller as you turn it. Also take your time, practice, practice, practice.
Always start on a straight line, in the middle of the line not at the end or beginning. If you find that you are wavering off the line come back gradually not abruptly, less chance of seeing mistakes.
Good luck
