Resolves huge liabilities in the products my business installs.
I own a custom shower door company that installs glass. Sometimes that install is in a child's bathroom of a successful, high net-worth individual that could become litigious without a second thought. You can bet your butt I am using this specific Loctite on all of the moving parts that could unscrew themselves. I am protected... thanks to Loctite 243. I have vast experience with this product being used on my projects that I liable for and I am 100% pleased. I recently got into RC vehicles and 243 is WAY too much for the 2mm Allen screws on my rig. However, it is perfect for high-risk applications that you hope to never visit again. It can actually prevent a real catastrophe!

It's the oil (etc) resistant 243, better than 242, in a big affordable bottle!
Big bottle, great price. 243 it the newer oil and chem resistant medium level thread lock.
