Can this caulking be used to seal cracks in concrete?

That isn't what it was designed to do. There are other products available at HD specifically made to seal cracks in concrete. Start here: Quikcrete Concrete Repair Sealant Internet #100318474 Model #862010 Store SKU #403016

amount of coverage/tube?

Coverage really depends on the user, I encourage being liberal with any caulking product to ensure the voids are filled and prevent cracking or separation. 1 tube should get you a couple or more windows done. 60"×36"

Can this be used on wood?

Yes it can be. Seems to work best if the wood is at least primed and not bare, however, it will also work fine on bare wood.

In the grout section of every homedepot there are tubes of silicone based grout. You can use them in place of grout in the shower or a bathroom floor. Do not try to clean or spread with water, you must use mineral spirits.

I wouldn't. Homedepot sells a product in the grout area that is intended for what you need in a variety of colors.

Is this good to use to seal an exterior door threshold where threshold meets concrete?

SURE, WILL BOND TO BOTH SURFACES, AND REMAINS FLEXIBLE.

Dynaflex Ultra is a great sealant!
[This review was collected as part of a promotion.] It's winter here in Vermont so I haven't had a lot of chances to use the sealant but had to redo around the base of a shower stall and used it for that. I loaded it in the cartridge and found it was easy to dispense and to smooth out once on. As stated, it was fully dry within 3 days but held up with use before that. I've attached a picture. I look forward to using more of it for exterior use once the weather is decent. I'll give painting over it a try too.

So far, so good!
[This review was collected as part of a promotion.] While time is the true test for quality on this product, I have thus far been impressed by this caulk. With cement board siding, I have had several opportunities for use, resealing joints and places where the original caulk had failed and cracked. I removed old caulk and cleaned up the sites to allow for better adhesion, then applied this product. This caulk was easy to apply and create a clean bead. Thus far this winter, we have had temperatures down to -20F and I have seen no cracking. Great product!

Was little thinner coming out of my caulk gun then I would have liked. As result quite a bit was wasted since the my expensive caulk gum would not hold a good tension on the tube. Dried quickly and good color match.
