Assembly Lube is a special extreme pressure lubricant, usually containing moly, used to lubricate high - load parts ( such as main and rod bearings and cam loads ) for initial start-up of a new engine. The assembly lube lubricates the parts without being squeezed out or washed away until the engine oiling system begins to function.

Silicone Lubricants are used to protect rubber, plastic, vinyl and nylon parts.

Graphite Lubricants are used where oils cannot be used do to contamination problems, such as in locks. The dry graphite will lubricate metal parts while remaining uncontaminated by dirt, water, oil or acids. It is electrically conductive and will not foul electrical contacts in locks such as the ignition switch.

Moly Penetrants loosen and lubricate frozen, rusted and corroded fasteners and prevent future rusting or freezing.

Heat - Sink Grease is a special electrically non - conductive grease that is used for mounting electronic ignition modules where it is essential that heat is transfer away from the module.

Sealants :

RTV sealant is one of the most widely used gasket compounds. Made from silicone, RTV is air curing, it seals, bonds, waterproofs, fills surface irregularities, remains flexible, doesn’t shrink, is relatively easy to remove, and is used a supplementary sealer with almost all low and medium temperature gaskets.

Anaerobic Sealant is much like RTV in that it can be used either to seal gaskets or to form gaskets by itself. It remains flexible, is solvent resistant and fills surface imperfections. The difference between an anaerobic sealant and an RTV - type sealant is in the curing. RTV cures when exposed to air, while an anaerobic sealant cures only in the absence of air. This means that an anaerobic sealant cures only after the assembly of parts, sealing them together.

Thread and pipe sealant is used for sealing hydraulic and pneumatic fittings and vacuum lines. It is usually made from a teflon compound, and comes in a spray, a paint - on liquid and as a wrap -around tape.

Alrighty then, quite a bit of information there, but for those of you that are starting to get motivated to do more than just check under your own hood; these chemicals can be quite helpful.
