I sometimes try to repair plastic parts for the XS mostly with 2 component Epoxy glue and it works quite well
other times i try to use Contact Adhesive on fabric like Jeans -- leather today on a Bomber style leather jacket. A hole at the elbow I tried to patch And rubber --rubber soles for boots and so
Cant get i to stick ... many times. Half the times it virtually falls off.
The instructions is let it dry a while .But applying to soon it wont stick and to late the same
I do have different Qualities Contact Glue. One is for construction in a small can It is Worthless.

Please give thoughts and instructions and brands
 
For leather and rubber repairs (shoes, mostly) I use "Shoe Goo" which is pretty much the same as E6000.

Very thick, very tacky and somewhat flexible when it cures.
 
Yes, Shoe Goo. Not Goop, which is different.
I have used Shoe Goo for decades. Add leather or rubber soles to boots, and patch leather.
If the rubber is smooth, it is best to rough it up first.
It is not contact cement. Just apply it heavily and put the pieces together.
It is very thick, goopy.
It was developed by a guy for the soles of his running shoes, to build up certain areas of the sole.
It remains somewhat flexable after drying.

3M brand automotive weatherstrip adhesive is good, I think the black may be a bit tougher than the clear.
For slightly more rigid joints but still needing some flex bumper patch adhesive epoxy works well.

I suspect the JB weld bumper repair is the same product.
 
The standard glue for leather used to be Barge Cement, in a yellow container. It was the stuff shoe repair shops used and it was impossible to pull apart. They changed the formula and put it in a blue container, and I don't know whether it's worse, better or the same. It never had wide distribution but occasionally you'd see it in a store, and occasionally you'd need it and search every store for it.

I've used YamadudeXS650C's Shoe Goo for various things (though not leather yet) and it's great. I've used it where you might use hot melt glue.

Best glue I've found for around gasoline is Seal-All. I'd trust it for stuff where glue made sense but gas was involved.

For putting a patch on a hole on a leather jacket elbow, there are stitches you can make from one side. Look them up and use "carpet thread" and a big needle made for it. Some surgical stitches (sutures) look cool, one looks like a row of X's.

I had trouble with the sole starting to peel at the front of my boots. Tried all sorts. I have always been a strong believer in contact adhesive, but it just would not keep the sole in place with time. Eventually I did the following:

1. Peeled back the sole a little and gave the rubber and leather surface a thorough clean and sand to roughen up the surfaces.
2. Switched my hotmelt glue gun on and left it to get super hot.
3. Used my electric hot air gun to heat both surfaces then squirted the hotmelt on, spread it about a little and then pressed both surfaces together and held them until the glue had set.
4. Then cleaned off and excess. If you try cleaning off the excess while it's hot you will end up with a mess.

The boots are showing no sign of the glue coming off and it has been about 5 months now. In shoe factories holtmelt is used a lot for attaching soles, but they have the special heated presses for attaching complete soles.
 
I have over the years bought these second hand and one new
Have 4 of them Sometime use on the motorcycle.
But mostly when cold winter days.
The one with a hole on the elbow is in fine shape and clean but in a low quality leather
very thin never seen so thin.
I have a cobbler long arm Singer sewing machine so i could have reached in to use it.
And the foot can be rotated so it can do it
But then there is the sheep skin on the inside
I did try to stitch from the outside hand stitching .. Pushing in the lining .. and it looked OK
But what happened was that since it was thin poor quality leather .The stretching at the elbow.
Using the jacket
Ritschh ..hhh at the new holes cracked the leather again. Immediately beside the stitches.,
New larger crack I was wondering if I should throw it .But since it looks above average.
and DIY is a hobby.

I for now tried a large patch On both arms . ( I have leather at home ) all the way down to the cuffs
The same color .. and tried to glue it It looks OK for a repair
And here are suggestions for Glue that will work eventually if not the Contact Adhesive I used now will

Not a answer for @Jan_P’s question, but for hard plastics and other rigid materials I have been using automotive body panel adhesive with great success. Just like an epoxy (2 part) but it sticks well to many plastics very well and cures rock hard. I bought several tubes of this from the local buy and sell. Think I paid $6 each and retail was around $50+. Supposed to use a dual plunger caulking gun but I improvise with a single gun. Not flexible at all though.

Just watched some interesting videos on the use of cyanoacrylate (KrazyGlue) with accelerators. Several accelerators available but didn’t know baking soda would do the same thing. Nice thing is the baking soda acts as a filler when used with the glue.

I am in no way a tailor, leather worker, or seamstress. But, I have a tool called a Speedy Stitcher that works great on heavy material. I have used it to fix backpacks etc. It is pretty easy to learn how to use it. If I can do it, anybody can.

I have one of those and used it and it worked great
When I use it again I'll have to re read the instructions I'm sure but I repaired strapping on a sidebag on one of my bikes and it's holding steady

A friend cued me into Panel Bond. Found it at an Auto Paint store and the owner told me he rents the gun for $5. The kits are in the $50 range around here.
