Review on 🔧 Permatex 54540 Pneumatic and Hydraulic Sealant - The Ultimate Solution for Air and Fluid Systems - 1.22 oz. by Lakeem Pickel

I was trying to caulk the threaded nipple on the bike's front master cylinder. Nothing I tried could seal it: teflon tape or teflon paste. Did some research and found this product recommended. It's too expensive to get 5 stars so only 4. If it was affordable it would easily get 5 stars. It works, my master cylinder has no leaks. This is a big bottle so it will last a long time. Unfortunately I don't need it often as I'm not a professional mechanic. At least now I have it when I need it.
