Touring - Tube glue for flag badges on my panniers?

I want to put a small embroidered flag badge on my packs of all the countries ,provinces and states i have cycled through, I was wondering if tube patch glue would be good for attacking them, my logic is that it is vulcanized rubber glue so I don't have to worry about losing the watertight nature of my packs and it would be flexible and would create a good seal to hold the patches on, is my logic correct? Though of super glue but it would crack if flexed, sewing I would have the seal up to be water tight again anyways.... thing tube patch gllue would hold?

Wow, I was wondering about the same thing! :)

Great minds think alike, we both quote Einstein too LOL

I like your quote better. :)

you want Mariine Goop

http://www.amazon.com/Eclectic-Prod-170016-Marine-Goop/dp/B000LNMVI0/ref=pd_rhf_shvl_1

altho any of the "Goop" products work well
Marine Goop is a little more pliable

you can also thin it with Toluene
but you need to do so in a can or glass jar, mix with metal or wood

if you put it in plastic, it will melt
work with it in a well ventilated area.

Goop is awesome stuff.
you can use it to fix a million little things.
i.e. saddle tears, glue innertube to tears on canvas, etc...

MARINE GOOP
is amazing
you can glue a patch onto an inflatable
let dry for a day
thin some goop
and paint goop over patch
this will put the patch under goop, and be just about impossible to remove.

for canvas patches
just use GOOP straight from the tube
I use an old spoke, coat hanger, etc...
smear the goop around
try some on a trial piece on some cardboard or something, to get an idea as to how it handles, so you don't squish a ton of GOOP out from the edges.
even if that happens, its pretty thick, so you can just roll it up with a coat hanger or spoke.

it will dry and last a very long time.
I pulled a Cars-r-Coffins patch off of my messenger bag after 6 years.
yes, it will dry, and stay put, grab a pair of channel locks, and start pulling the patch off

you can also color it with paint

its widely used in the world of R/C gliders, etc...

my grandpa once knew the guy who invented Shoe Goo
pretty much the same stuff...
but how many people actually repair a pair of tennis shoes, etc...
few...
so we ended up with about 100 gallons of the stuff
what did we do with it?
my grandpa bought a old yellow Navy surplus life raft, that was full of dry rot.
used the air compressor to keep it inflated, and painted it with thinned down Shoe Goo
talk about a fire hazard!

No, it won't work. It's a rubber cement, designed for sticking rubber things to rubber things. It's rather unlikely that either your panniers or the flags patches are made of rubber. There are any number of suitable fabric glues; your local fabric store will sell you something suitable. (Make sure you get one that won't wash out; many fabric glues are used as temporary glues, intended to hold while something is sewn together, and then wash out.) The one thing I'd worry about is that many DWR finishes are hard to glue to; the thing that makes them water proof makes them glue resistant.

I'd sew them on. It only takes a few stitches per inch to hold something like that in place. treat the back side with a seam sealer. if you do a bunch at once, it'll be easier to seal.

Use Shoe Goo. Like $5 at Wally World.

I take the time to sew on the patches and then add some shoo goo to where the thread went into the bag to seal
small holes

.. there are fabric adhesives, I'm trying to re attach the seam tape in my rain pants with some, as it comes loose.

I sewed on patches to my sewn together panniers, my Ortliebs stay dry by not having holes in them.
Those bags being thermally bonded hot melt glue or Iron on patches may be an option ,

but the temperatures would need to be controlled to be low enough to not mess up the structure and waterproofness.. .
