Suggestions for where I buy a larger patch? Tear aid? Bicycle inner tube patch (others claim its the same material and is definitely more widely available).
it depends on how you applied the poor patch. It looks like you not only wrinkled the bladder material you stretched it a bit so if you patch over a patch the wrinkle that is now under your current patch will just grow because the bladder material can no longer lay flat. Then you will have to cut out your second patch and make an enormous patch.
You can buy a 5 foot roll of tear aid type a for about $25. remember type a, not type b (type b is only for vinyl).
And yes I have gone through more than one roll of tear aid in a single year. Something about putting a patch on a patch on a patch lol.
Inner tube patch is slightly different it is designed to take 100psi so it is thicker and won't stretch as easily as tear aid type a. So yes it is the same stuff but I would still use tear aid type a because it will stretch with the bladder better.
When using a jumbo patch don't forget to put a paper towel inside the kite so you don't accidentally tape your bladder to itself.
Do not weld a seam of your actual kite on your first try. You will have to practice on an old bladder if you don't have any old bladder ask around, someone will gift you several feet of old bladder to practice on.
I was the same way when I first started fixing the bladders on my kites oh my goodness the messes I made of my bladders. I eventually figured it out, but even I sometimes give it up and just buy a new bladder.
