Waterproof, saltproof, roadproof paint

A long time ago I put witness marks on all the critical bolts on my bike so that I could see if the marking was broken that means the bolt has loosened.
I leave the bike outdoors uncovered and I ride it year round.
The seasons of weathering have dulled the paint used to make the markings and now I forgot what I used.
I need a paint, hopefully something convenient I can get at home depot, that can withstand the weather to redo my witness markings.
Anybody else do this and can make a recommendation?

How about nail polish. That stuff gets as hard as a rock.
You can color coordinate to the bike.

I don't know how well nail polish weathers but no more than you need it's worth a try. Otherwise most any exterior oil base paint will work. Any paint exposed to the elements will deteriorate over time.

Google paint pen. I got this at my local home store and used it on the lug nuts of our bucket truck. Over a year later and the marks are still there. https://www.menards.com/main/tools-h...7307190&ipos=6

I use something commonly used on aircraft. It's a little tube of paint that you squeeze out onto bolt heads after inspection. I've got some over 10 years old that is still in great shape though the plane lives in a hangar. The link I included is to an aircraft supply company but you may be able to find it cheaper elsewhere as it's sometimes used in industry as well.
