Black limestone sealer/enhancer - Which is best

[Whitey]

Can anyone offer some assistance.

My black limestone patio has been down 1 year now and has faded to a steel grey.
I have narrowed it down to the following options:

Weiss FT Plus
Miracle 511 Enhance & Seal

Can anyone offer advice/preference on either.

Thanks.

Both are very good products. Weiss provide samples so that you can see the effect for yourself on your own paving. I seem to recall that Miracle is not available as a sample.

That's correct Tony, Miracle stockest over here doesn't really send out samples unfortunately.

It seems like an anti-marketing move when most of your strongest competitors send out FOC 50ml samples (some send out far more!) which can only cost pennies and surely has to be more effective, in terms of return-on-investment (ROI), than, say, running an ad on Google, as the enquirer is already definitely interested.

Still, they obviously know their trade better than I, and they're probvably making a damn sight more money than me, so I'll keep my councel to myself.
