tile glosser?

I recently installed a ceramic tile floor for our kitchen (my dummy self thought it was porcelain because the store had it under the porcelain area and I didn't bother checking the box, but thats another story). Anyway we couldnt argue with the price so I took the tile even though it was not as glossy as we would have liked. When wet (of course) the tile is super nice and shiny but then drabs out pretty hard when dry. We can live with it, as again price was a huge factor in our decision, but I was wondering if there were any glossers or sealers that could be used over already sealed ceramic?

I found something online called glaze gaurd but never heard of it so I thought Id hit this place and see if you guys ever used anything. We also use a sealer/cleaner/glosser for our vinyl grip strip floors in the basement which "Says" it can be used over tile but Im weary on that and its not really a super sturdy glosser.

Thanks
