For those of you who are curious how I rust proof these stitch welded areas especially the hollow cavities please have a look at this video. Skip forward to 7:00 for this part.

1. First I blow the cavities with compressed air
2. Then I peek inside with a boroscope
3. clean with a bit of wax and grease remover using the same technique in the video
4. coat with liberal amounts of epoxy primer
5. spray cavity wax after everything is painted. I haven't done this step yet.
