This sealant remains flexible even at high temperatures, with a temperature range of -60 degrees Fahrenheit to 500 degrees Fahrenheit, which allows for repeated disassembly and resassembly in metal to metal applications. Versatile and vibration resistant, this tacky formula allows for unlimited assembly time and stays tacky for repeated use without reapplication. Ideal for use on cars, trucks, boats, tractors, snowmobiles, engines, lawn mowers and chainsaws.

Review: Wish this was available in the 80’s - Outstanding metal to metal contact sealer. I sure had doubts though. But it turned out perfectly. No gasket required. It really doesn’t fully cure and seals out fuel like it was the plague. Woulda been a game changer in the late 70’s for me. lOl
Review: affordable and works - Worked on my vintage car. No issues for 2 years .
