I dont know much about patches either but here is one thing I found out the hard way. Slime Skabs dont work for much other than to get you home from the ride your on. Slime skabs are like the ones you described in that they are little patches that you peel off and stick on like a sticker. There is no glue to be applied. From what I have read it is best to buy patches that have glue that you apply to the patch and to the tube. They are called vulcanizing patches I think. Hope this helps a little and good luck.
