Definitely get the drop done, but can be messy. Make sure just to let it cure fully.

Used it for my windshield gasket
It worked great for my Kia Spectra windshield gasket that kept coming off. When I purchased it, I did not realize it was going to be black and I have a white car, but I was able to get it on without messing everything up. It hardened pretty quickly and I am satisfied with the result.

Works good on oil pen gaskets
This works great, I used it to ensure no leakage from a new oil pan gasket on the front and the rear. The sealant starts setting up within minutes allowing installation to be done quickly. It's been just over a thousand miles since I have applied this and there is no leaks.

Not being used as a gasket
I hope when I use it, it will self level. Not really using it as gasket material. That's why only 3\5. Nothing bad about the product. So just use it as intended and I bet it will be fine.

Not just for engines
I used this to replace a rubber seal on the door of a air fryer/oven. With its 600° heat resistance, it worked great.
