I'll look around for a source of the white tarps. I can't remember ever
seeing them in the local retail stores.

However, not that you mention it. I met a boat owner, several years ago who
had made a full boat cover from white tarps and she claimed it had lasted
about 6 years and was still solid enough to use for a pattern for a
replacement one.

Thanks,

There might be. The pigment used to make those is just aluminum powder,
but there are a lot of additives to make it work. If you can get a
small piece first, rub it against the mast or boom to see if anything
transfers. Over time, you may get some transfer if the wind whips it up
against metal. Don't buy the silver for "reflective" properties. The
best for that is a good quality white tarp. Search for "Armorlon" for
one supplier of good stuff.
