what size tube is the glue?

It doesn't really matter. The cement tube in the patch kit will be dried out within 10 months of first use. As a practical matter, I've found that these Park patch kits are a single use item.I'm a verified purchaser of this Park VP-1 patch kit. As I suggest in my review, you can buy good quality Kenda inner tubes for about $5.75 each, shipped. I now carry a new inner tube in my panniers and would install that instead of patching. However, I also carry a replacement Park patch kit for the unlikely event of having two or more flats in one day. That event is so unlikely that I prefer to carry the small, light Park patch kit instead of a second new inner tube. The cement tube in the Park kit will remain fluid for many years as long as it is kept sealed and unused.

I have leak on the rubber right under the valve, would one of these patches work? The valve part and tube material seem to be a bit different.

Possibly because of the inflated pressure pushing on the patch and possibly sealing the hole, but probably not! Sounds like an old tube with dry rot separating the 2 materials. In an emergency I might try it, however I would replace the tube.

It shows two different kits that look exactly the same except for the container and price. What's the difference? Thanks

From the looks of the new add is that one is last years product and the more expensive one is this years product ! I'd go with the new one ! Just because the glue would be fresher. It's an awesome patch .. I know that for a fact. Significantly better than a walmart product and significantly better priced than a bicycle shop. I'll probably order a new one here ..

is the glue/cement enough to patch 2 small patches?

Depending on how aggressive you are with the glue at least 2 patches. However, once the break the seal the remaining glue will be good for about 6 month. Beyond that you are pushing your luck. It does not matter which brand you buy. If you have broken the seal, toss it at the end of the season and buy a new kit. On a side note: something rarely seen in the instructions, before installing the inner tube, check the inside of the tire to insure the object that caused the puncture is not still embedded in the tire!
