Honestly gorilla glue will hold it fine. Same thing happened in my girlfriends escape due to the heat and I used a really heavy duty glue. I applied a decent bead all around the edge and put an x in the middle. I worked my way around it folding the edges in as I went. I did get glue on her door which is a vinyl so I was able to get it off rather easily with a mr clean magic eraser. Just take your time and be careful. If you have cloth along that piece that fell off then you will need to mask it off before doing any work; I should have done the same lol. Ohh and leave the windows down over night or it will be a hotbox of that nasty stench.
