I have never used them but might be good to carry, do they
work in general? They seem like could be much fast than
removing the whole tube if you can find the puncture. I
always carry spare tube but only one so thinking ahead now.

Not the true vulcanizing bond of the zinc-rich Rema patch
system, but maybe OK at the margin.

True chemical cross linking is a superior approach to fully
bond patch and substrate (tube).-a Stick-on patches use a
mere adhesive.
Do carry some alcohol wires with your patch materials.

I tried them and discarded them. They don't hold... I wouldn't pump
them up to 80 PSI... maybe 40... May be 30....

applied, let it dry good, then patch on top and use a clamp
to hold in place for awhile. Mostly overnight as I just do
them on work bench and they are quite strong.

My cheap mini pump I managed to get front 20 inch tire to around 63

you lose if something goes wrong. I am thinking the best option is the >Leyzene I had and lost, it was good to at least 80 and the flex hose was

I getting paranoid now with flats. I went 4.5 months and 4750 in miles
on the catrike no flats. THen I have 2 within 3 days. I googled AI which >suggest that a Trike arrangement would generally be more prone to flats
that 2 wheel road bike. I rarely flatted on the road bike maybe 2-3
times a year in high mileage too.

I use Marathon Green guard tires which have protector strip under the
tread. I have very little trouble with flats, but a year or two ago I
was getting a lot of flats because of bad rim tape placement.
Did you check out what andrew said about plastic rim tape? He said
that they can stretch down into the nipple socket and produce a round
hole or cut. My new 20 inch wheels have a blue rim tape and I don't
know what it's made of. I took them off and put on my old 20 inch
wheels. I'll check them out when I get back from Ohio next week.
I carry two extra and tube repair stuff, two 406 tubes and one 599, a
mini pump, and the new battery pump. I also carry tire carcass repair
patches I could have uses one when I ran over a broken beer bottle
years many years ago.
As for trikes being more prone to flats, the fact that you have three
tracks to avoid instead of just one....

- They don't stretch, so it you happen to be using a tube on the smaller size for the tire it will sheer the adhesive and promptly leak.
- not a good long-term repair, usually good enough to get you home.
- The adhesive doesn't adhere well in the cold and will stretches in the heat (not the patch, the adhesive) so can allow the patch to 'migrate'
while riding and possibly leak.
I tried them for a while and found the times they work well are so few
and far between it's not really worth it. Unless you're trying to
minimize the weight in your tool kit, just carry a 2nd tube.

That's me -- I prefer carrying a second tube, even if I will carry a
patch kit, just in case I get multiple flats on the same ride (as I did earlier this year). I don't care that much about the weight.

Like a regular patch you have to sand the tub e before applying the
patch. But I now conider this an emergency fix only and replace with a
new tube. I have never managed to put a patch on recently that doesn't
leak - slowly at best.

Even with the Park ones, since the fix isnrCOt permanent unlike a regular patch, seems questionable why one doesnrCOt fit new tube, and fix at onerCOs leisure at home.
ItrCOs a bit of moot point really for myself as the commute/utility bikes that use tubes have tyres that are designed to be difficult to puncture so itrCOs a rare occurrence personally.
