Wondering if anybody has experience with this product, if it's to
be used on metal...and if it holds up.
It may be that it needs to be drier before the gold is applied.
Normally, it’s applied with the sizing just barely still tacky, if
even that, rather than wet.
And yes, people use it. Check out the work of David Huang. If you’re
not familiar with his stuff, you’ll enjoy seeing what he does.
Wonderful holloware objects, often lined or decorated with gold leaf.
I’ve asked him why he doesn’t electroplate, and he says he prefers
the look of gold leaf. Quite different, perhaps richer in appearance,
but also just a different surface, and works well for him. Plus,
unlike Kum Bo, it works on metals or materials other than silver.
Much of Davids work is copper, and the gold leaf is very rich
looking indeed on those objects. On David’s work, of course, these
are decorative objects, not jewelry to be worn. I’d expect it to be
less resistant to abrasion or wear and tear than Kum Bo or
electroplating, since the bond is essentially glue, not metalurgical.
But used properly on carefully chosen surfaces, it should be quite
servicable within those limitations. You’d probably not want to put
a gold leafed item into an ultrasonic very long or to steam clean the
heck out of it either.
