Tar as the Primer-Coat of most steel in the future
Seems to me as if tar is the best medium or mode to design a Metal Primer
Coat. In which you coat all iron bridges with the tar and paint over the
Whether the tar dissolves rust itself or whether some acid in the tar
matrix is the dissolvent leaves plenty of room to *design* a tar that is
perfect for each metal
primer coat. Some metals may need a higher dissolvent and thus a better
The characteristic of tar in that it adheres to the surface of metals is
characteristic. And the secondary characteristic is the dissolving power of
eliminate any and all rust.
Before this observation, it was thought that tar is only a passive rust
The new thing I am saying is that tar has a chemistry of not only passive
rust prevention but has an active chemistry of actually dissolving rust.
Whether that dissolvent is innately within the tar chemistry itself or
whether it is some additive to tar.
I would hazard to guess that if a tar were designed for old automobiles as
a primer coat that those old automobiles can last into the future
indefinitely. And that any new car rolling off the assembly lines were
given such a tar primer coating would also last indefinitely as long as the
owner would occasionally peel off old tar that was coming loose and applied
a new coating of tar.
But best of all, instead of steel bridges and steel statues lasting for
only "centuries" as a normal lifespan, with tar primer coating I envision
these steel structures lifespan to zoom up into the milleniums as a normal
lifespan instead of mere centuries.
Some will complain that a paint job could never say match the beauty of a
stainless-steel structure of the St. Louis arch. And that this arch will
never rust. But it will rust, if I am not mistaken, for stainless steel
eventually gets those pock mark rust spots. And that the stainless steel
can also enjoy a huge expanded lifespan if it were given a tar primer coat.
But people will complain that no paint on the surface of the tar can match
the natural beauty of stainless steel. I would argue that if you found the
correct "painter" could make the St. Louis arch even more beautiful than
its present state.
Another great application is ship hulls. Now, I wonder if barnacles and all
that other junk stuff that sticks to ship hulls, whether a teflon like
paint coating would detter that stuff. And whether tar for submarines is
the best coating for secrecy in detection. As well as preserving the steel.
Two Theories as to how Tar Works to dissolve Rust:
(i) Tar chemistry is such that it is a dissolvent for iron-oxides
(ii) some additive to tar such as sulfur makes for a slight pH acid which
