Attaching ivory keytops

Matt,

It seems like the thickness of the tape would make a difference in the height 
of the keytop.  This would be a particular nuisance where you only have to 
glue on either the head OR the tail.  Are you talking about a whole keyboard?

I was given much good information a few months ago on the same subject.  
Check the archives.  I'd say at least half of the people recommended PVE-E glue, 
and some suggested using titanium dioxide(paint whitener) to be certain that 
there was no bleed through of keytop color.

The tape sounds easy, but how does it look and feel when you're done?
