K&W 401612 Copper Coat Aerosol - 9 Wt Oz High Tack Sealant for Metallic, Hard Surfaces, Rubber Gaskets | Automotive Adhesives & Sealants

Have used this product for several years works great 👍

Used this on my head gasket for my WRX and on my intake gasket sealed everything up tight got about 2k miles on it now. I normally don't use this but I had some damage to the block from head gasket failure and I decked the block myself and head was .001 out and figured I'll use this to help seal it up no issues yet.

I always use this Copper Coat for head gaskets, It just seems to work great for me.

Copper Coat has been around a long long time. Sometimes old school works best. Sealing technology has come a long way. Many of todays engines use molded rubber gaskets that seal well. However I had a 2008 Jeep Wrangler with a small oil leak that was a bear to fix. After pulling the engine 3 times I finally discovered the leak was from the multi layer steel (MLS) head gasket. A light coat of Copper Cote fixed the problem.

As a semi-retired mechanic I've been using Copper Coat for over 45 years now, and I feel it's one of the best gasket sealers ever made.I've never had an oil/water/vacuum leak after using this stuff, and if the parts ever need to come apart again the gasket comes right off without sticking/tearing.Sadly, I can't seem to find it in the can with dauber anymore, but the spray works just fine, it's just a bit messier due to overspray.

Good stuff. Been using it for years.

nice

I always use this on my small engine builds.I use it on head gasket etc for a tight long lasting seal.
