Marker for Drysuit Leak Test?

[Fin Finder]

I'm conducting soapy-water leak tests on my old drysuit. Any suggestions on how to mark the leak points once they're found?

So far I've tried red and black sharpie markers, white-out, and memory. None are working very well.

I used common chalk.

Yellow grease pencil. We use them underwater on the hull to mark things you can't see once the boat is hauled out. https://www.amazon.com/Brite-Mark-Permanent-Underwater-Marking/dp/B0000DYNS4

A regular stick of white chalk works fine.

Yellow/white grease pencil or chalk.

Or you could put a pin there.... It works very well... the hole will be right there.
