I am currently restomodding my AAR and have been using the stuff on all the natural pieces. We'll see how it holds up and prevents corrosion, seems awesome so far! I have been spending a lot more time in the kitchen lately (using wifey's oven and cookie sheets) - preheat my parts to 180~200 degF and have fun brushing parts with the kids.
Make sure you have good light to work with, much easier to see if the workpiece receives complete coverage, easy to miss a spot if you have poor lighting.
