The outer skins I cut up last week had a lot of tabs that needed to be filed down.
The doors needed some JB Weld cleanup. I tried removing the dried excess with a razor blade but it just wasn't doing anything. I was just scratching up the surrounding aluminum.
I remembered using a brush from the accessory kit I bought with my dremel a few years ago. I couldn't remember which worked best tho.
After a little experimentation between plastic and wire brushes, I found the wire one worked the best. After slowly going over the edges of the excess JB Weld, I let the brush lightly clean the rest of the aluminum. 
After letting the piece cool off, I wiped it clean with some water and a towel. After drying and re-checking the edges, it will be ready for priming soon!
On to the other doors!
