What's the actual failure rate on those cheap crimpers? I've seen guys go through a whole bag of pins before getting one that holds under load.

Sounds like you made frosting soup... and then frosting concrete.

My buddy kept his in a sealed ammo can in the basement. Worked until his sump pump failed and it floated away.

Isn't it crazy how fast that kind of wear adds up? I'd take pictures of the specific marks with something for scale, like a coin, and email the park superintendent directly. A dated photo log from a visitor can sometimes push things up the priority list for maintenance. They might need that to get extra funding or volunteers.

Lol, famous last words. I tried that stuff once and my repair looked like a toddler finger-painted with oatmeal. I definitely do not know how to apply it.
