Sealer coat for stone countertop

[weelis]

We have "Mexican stone "(Not tile) for kitchen counter tops which I have just stripped of all sealer etc.  My question is does anyone out there have a "favorite" sealer that they use in  similar situations?  Thanks.

What is Mexican stone. I live in tx and have never heard that term. If it's a natural pourus stone like travertine I'd treat it as such. Which is quite costly for good sealer and also why I won't do real travertine in a house if it is expected to always look like new.
