How to fix wetsuit seam tape?

My son’s suit has a couple of places were the stitching could cause chaffing due to failure of the seam tape. How do I fix this?

Thanks, Graham

Other options:
Buy a roll of seam tape (harder to find in small quantities).
Any surf/dive shop (easy repair).
Reglue tape w/AquaSeal (probably would work, haven’t tried it for seams).
