It works with a 0.010" gap like the tech specs claimed!
Regular loctite is not suitable for large gaps up to 0.010" but this is. HOWEVER like the tech specs say, you want to wait 3 days for a gap that large to reach maximum strength.

Red as a tomato
This product is red, therefore it is superior to all non red products. It also did a good job keeping things real tight on my vehicle if that’s what you plan on using it for

Bottle was only half full
It’s a great product. However, when I received the bottle, it was only half full… 🤷♂️
