I've heard nothing but good things about Dupont Bulletproof and am getting some in the next day or two for my marble back splash and counter.

I wouldn't count on any warranty support that claims to replace $1,000's worth of stone counter from a $50 bottle of sealer. For that warranty model to work, they'd have to pay out on next to no claims.

That's like paying $100 for a new tire on your car and the manufacturer saying they'll replace your car if the tire blows. Just not economically possible.

Mine is Stone Tech -- made by DuPont. Not sure if it's the same one you are talking about but I've had it down just short of 4 years. I have no complaints with it.

I would just get the sealer and don't worry about the warranty. Not only is it like buying a tire and thinking they'll replace your car, you don't want the counters replaced, the cabinets and slash possibly damaged, your sink and plumbing upset (which I'm sure they won't cover), and that's assuming you overcome the it wasn't applied correctly and it wasn't maintained correctly exceptions.

They said repair or replace, and chances are the only thing they will do is tell you that you that the sealer either wasn't applied correctly or that it is a wear area where you should have reapplied sealer and then apply a poultice and tell you to reseal the area. I doubt they do pay out on any replacements. But it sounds good.

Marble is a very durable stone and can be worked with. Most sealers will do a fine job of protecting from stains. They do need to be reapplied, especially in your heavy traffic areas. I've only spot resealed in some wear spots, but I've had tomato sauce, chocolate and other stuff splattered in places I didn't see and clean until the morning after. No stains. In the wear area by my sink, I had a light tea stain, but it came right out with any special efforts -- a little cleaner and a light buffing. If it were worse, I'd have been here looking for a poultice to put on it. To me, that's less of an issue than waiting around to have someone come do it for me, dealing with the dogs while they do it and having to listen to "don't you know this about your marble, honey."

Get the marble and enjoy it -- or don't. Don't get it thinking miracle products will change the nature of the stone and make it okay for you. Be okay with the stone itself if you are going to get it.

Thanks for the responses! The sealant is called ProAdvanced by Dupont. I did go back and speak to the woman at Daltile and got some info.

It is indeed limited in what it covers (i.e. just the piece of stone damaged, no plumbing or repairs to backsplash etc).

I am going to get a sealed stone to test and also test out the product I bought via Amazon. Can't hurt. It's definitely cheaper than the DuPont product.

I am having new honed Carrara marble counters sealed by the fabricator with Bulletpoof, and I will purchase the warranty for $350. You can only get the warranty if the sealer s applied by a fabricator licensed by DuPont. I have read the warranty, and it does promise to repair or replace. Frankly, staining seems pretty easy to prevent (as opposed to etching), so the warranty is probably unnecessary, but I am buying it for peace if mind. My fabricator also gives you the remainder of the sealer and a free bottle of the daily cleaner, which is about $40. Not alot to pay for peace of mind. By the way, my fabricator also rehones on site for $90 an hour. To rehone my entire kitchen (and I have a crapload of marble, almost three large slabs) will take him about six hours. $600 every couple years to get rid of the inevitable etch marks is a small price to pay for the beauty of Carrara.

This sealer doesn't work. i used it on my Brand new Marble Kitchen Island. i coated the island 3 times and buffed it in with each application. I have glass rings, spots everywhere. Do Not buy this!

Glass rings and spots are etches though not stains. A sealer will stop stains but do nothing to stop etches sadly.

We used this in our kitchen remodel 6 years ago (statuario and nero marquina marble) and it works incredible on preventing stains. Had wine spill sit overnight unintentionally and no trace. Only issue we ever had was Nutella, which is its cryptonite. Other than that. Great product. I think that DuPont sold the professional product to someone else, but not sure. Laticrete maybe?

Angus is right. I have been using the Dupont product for years on my porous granite but the last time I bought it is was sold by Laticrete as Stonetech Bullet Proof Sealer. Never had had a staining problem with it.
