[TheForge] krylon clear for exterior use

[Catherine Jo Morgan]

I haven't run tests on this myself, but a usenet blacksmithing and
metalworking thread reported that someone else had run tests and found
that Krylon clear didn't last well outdoors. Unfortunately it's the
sunlight that seems to break down most clearcoats outdoors. Under a
roof, it may fare better.

If I had to finish something now for this situation, without running any
tests, I'd use General polyacrylic in the stronger version, their
waterbased polyurethane - a brush-on varnish. It requires good
protective gloves and fair ventilation, but brushes on well and is a lot
less toxic than Kamar too. For use directly on iron I'd add a rust
inhibitor, but over gun metal finish I'm not sure. Guess I'd have to run
a test after all.
