Sure, but as has been pointed out, there is a difference when the
preservative is part of the original intent and design, incorporated when
new, as opposed to looking at something that is weathered and saying, I want
to stop the weathering process, so I will seal it from the elements by
applying an impervious coating. And yes, preservationists often bring
artifacts into climate controlled environments, but some are to large for
this. These cases present a real problem, which is not usually solved by
applying a sealing surface.

Even with these coatings, I doubt the vehicles mentioned would be exposed to
Saskatchewan winter roads. Because even these coatings are imperfect, over
time resulting in the problems that people here are talking about.
