Gasket sealers are great when used properly but gasket sealers can create a ton of grief if used improperly.
There are gasket applications where sealers absolutely must be used and some applications where they must never be used. Whether you should or shouldn’t use a gasket sealant will normally be included in the gasket instructions. The instructions also describe the type of sealant as well as where and how to apply it. Bottom line, always use sealants where they’re required, never use them where they aren’t! Always use the proper type for the job, and always apply it according to the gasket maker’s instructions.
