So I re-did the patch. I sanded the old glue off (as good as I could without destroying the rubber) and re-did the patch but it slow leaks already.
You didn't mention it in your OP...so I have to ask. Maybe your personal budget can't afford it. But if you're going to be dropping the $$ for these various patch kits...why not just spend the money on a new tube? I mean I patch tubes myself when it's optimal. But when the leak is on/around an old patch, or near a seam of the tube, I just trash that tube and replace it. I find it nearly impossible to get a patch to work when glue from a previous patch has already dried. It requires way too much sanding. And if the leak is too close to a seam the patch won't make a good seal. I'd just go with a new tube.
