Just your usual low end stuff.  Seal the seams, they do quite nicely.

I like the roll on bottle, which is really a small bottle with a sponge head, they sell at Walmart.  Set your tent up in the sunlight, then just go in and apply.  It takes minutes and can actually be done at your camp.  Do the seams, then look for pin holes of light, dob those.  Zippers are problematic but you can beef them up a little with the blunt end of a wax candle.  

A lot of folks like the sprays but those things leave a big ugly spray path like you took a paint can to your tent.  

Now keep in mind, no matter how water tight your tent is, you still have to go in and out of them.  Placement is just as important.  If the prevailing wind is from the west, not a good idea to put your door west.  Identify even plan on your inside low spot where water can gather.  Other than not setting it up in low spots and sometimes a good idea to divert running water with a light ditch, that's about it.  

I have an old thread in the archive about one of the Survival Forum camps that we got hit with a Blue Northerner.  I was in an inexpensive Wenzel 7x7 and stayed dry as a bone.

No problem, enjoy your tent.

I bought an old Wenzel many years  ago, dome tent a model back then that had a tunnel to a second pup tent for the kids.  The few times a year I need a big tent, I still use it.  It was one the first clip up models so very fast set up.   Most of my truck camping these days though is either a 7x7 low profile, way better in colder temps, or pack tent, but when the wife goes, she likes creature comforts like chairs, lamps, to read by, cooler in the tent etc.  

Anyway, nylon is nylon and that gauge that gauge so if you take care of it, one tent will do most of us as good as another.  I really like my better tents more but then they're the smaller ones.  You run into some inherent problems with big tents, like open the door in a rain way more space to let water in, that brand can't fix.  To fix that stuff, now you're talking style change, for example guide tents with stoves, tunnel entrances etc., that are not going to be fast easy setups.
