Tef-Gel is a synthetic based PTFE waterproof lubricant with anti-corrosion and anti-seize properties. Tef-Gel does not break down in salt water or detergents. Tef-Gel is a US Navy specified non-lanolin synthetic formulation. Lanolin, an extract of wool used as the base for the popular anti-seize product can absorb small amounts of moisture which will allow for corrosions and seize your stainless steel to aluminum joint after a few years. The paint will blister in the surrounding area.
Use a dab of Tef-Gel when connecting to aluminum with stainless steel screws. Tef-Gel will eliminate the risk of galvanic corrosion and the paint blistering it causes not to mention that you will be able to unscrew the fastener years from now when you may have to.
