Neat & Effective: Perfect Silicone Solution
I used this black silicone to seal a customized USB port on my car dashboard, and it looks flawless! No odor, easy application, and it does the job perfectly. Couldn't be happier!

It was dry
The product was dry at the tip of the tube. I had to dig with a thin screwdriver in order to reach the soft part. it worked.. but the product should be too old so it will not get dried up.

Solid sealant - saved my aftermarket brake lights🤷🏼
I used this to seal around a set of aftermarket rear brake lights after my original ones let water in and ended up getting damaged. Applied a clean bead around the edges and let it cure for the full 24 hours. The day after, we had heavy rain and so far it's holding up great - no leaks and the seal feels strong. It used just over half the tube for both lights, so if you're planning a bigger job or sealing more than one area, I'd definitely recommend picking up two tubes just in case. Will update if anything changes, but so far this stuff is doing exactly what I needed.

Very good stuff!
Very solid drying silicone for most auto jobs.Works great on the china rails on Ford and Chevy small and big blocks.I have used it on oil pans and valve cover gaskets and have never had a issue. I buy it buy the case because the parts stores are much to high, I keep it in the house so it will last much longer due to temp being controlled.

防水シーリングとして使用
グリルマーカーを付けるためにグリルに穴あけをして裏側の配線ごと接着、防水シーリングとして使用。一晩放置で完全に固まって3ヶ月経ってもグラ付きは無いです。効果は文句無し。ただチューブ製なので作業しているとやがて手が真っ黒になって洗い落とすのが大変になるので手袋が必須です。
