It's hard to tell from the site, but wouldn't it be easier to simply fill the emblem holes and custom-cut new emblems from the vinyl lettering/stripe material and just stick-em on?
Of course, it just wouldn't be the same as the raised bowtie on the front-hood of some of the models... but it wouldn't collect as much wax build-up, that needs to be removed with a toothbrush, around the edges either.
I certainly do like the idea of "Custom Emblems" though.
