Tube Training?

Track where you get the holes in the tube, you may have a tire pressure, wheel/spoke issue, rim strip issue or not getting the tire "clean" after a puncture. With Gatorskins you should be safe unless you just run over everything you see. ;-)

No experience with the sealing tubes, but I would guess they are not the solution or more of  "us" would be using them/ talking about them...

The tubes you are looking at are not generally used in a road bike, basically they are just regular tubes filled with that green slime you used when you were a kid. It basically just adds a lot of weight to the wheel that most of us don't want.

I read your other post about getting a lot of flats, looked like all but 2 were user error. And the two times it was not user error, the metal was enough to go through a gatorskin, and a liner, so the slime wouldn't have done any good in that case anyway.

If I were you I would correct the user errors then just stick with the gator skins. 

As far as the other sealant you were referencing. Some people are running tubeless rims and tires these days. So it is just like a modern car tire, smooth rim and no tube at all. You need a rim that is capable of running tubeless, then a tire that is capable as well, then you have to add a certain type of sealant when blowing the tire up. 

A tubeless setup invites a lot more user error so I would stay away from that if I were you.

 We just did the ride from Key Largo to Key West and back (220 miles) and there were lots of flats in the group but only one in our group running Gatorskins. We put 110-120 PSi in the Gatorskins and had no issues.... I will say I changed all four of the tires upon our return.

Tubless tires look like a mess and not sure the slime would do any good.

Good luck maybe try your Gatorskins without the liners and at higher pressures to prevent pinch flats and make the tire "harder" but thats a trade off too. 

Bummer on all the flats.  Hint, call the county or city road maintenance depts.  Up here in central east coast FL they put in a bike lane on what was a restricted highway (causeway) that people were riding on anyway.  All the causeways seem collect a lot of debris and one of the LBS put up on there website the numbers to call for road side cleaning.  Apparently if they get a call they must act on it. 

Went back and read your old post again. Unfortunately I don't think there is an equipment change that can fix your problems. The slime is not going to do much if anything for you, you already have gatrskins and liners. About the only thing equipment wise might be to try Specialized Armadillos instead of the gatorskins. Quick google search found a few posts of people saying the Armadillos are tougher than the skins, the ride is more harsh, but supposedly they are more flat resistant.

Other than that I'm afraid your only option is to be more proactive in avoiding road debris, easier said than done sometimes. Hopefully now that you have the skills to avoid the user error flats, the overall number of flats should come down. Any chance to get off the shoulder and ride in the actual roadway? You do have the right to ride in the lane which is usually much cleaner than the shoulder, however it is not always feasible given traffic and speed limits, etc. 

If all else fails you could get an indoor trainer or rollers, but that tends to suck the soul out of you so I do my best to avoid it. 

If you do have a road with a relatively low speed limit and decide to try riding in the road, make sure you "take the road" so to speak. I find if I hug the white line too much it encourages drivers to attempt risky passes, if I am further out in the lane they tend to wait for a good time to pass and give me more space. I usually hang out in the right hand tire groove, works well for me around here.

Another option to look into is group riding. Not sure what is available in your area, but the harassment from cars goes down considerably when you have a group of 10-20 people. Much safer road riding when you have some people with you.
