I have a Mountain Hardwear Trango 3.1 (a four-season tent) that lost the hooks on its rain fly. They simply became unglued from the inside of the fly a little while back. For those not familiar with this particular tent, the inside of the rain fly has about a dozen plastic hooks that it uses to attach to the poles of the tent to hold it on in all sorts of bad weather. The hooks themselves are connected to a bit of fabric which is in turn connected to the fly. In this case, the hooks are still connected to their fabric pieces, but the fabric became disconnected from the fly.
I'm not sure what happened, though my suspicion is that I let the tent get too hot and the glue lost its hold. This happened a few years ago and fortunately I was able to find and collect all of the pieces that fell off.
Now I want to reattach them for an upcoming trip (in about a month, so I have plenty of time) and then re-waterproof the fly as the waterproofing is coming off as well (presumably for the same reason that the hooks came off, though it probably doesn't matter). Waterproofing is easy enough, but I'm not sure the best way to reattach the hooks. According to the MH website, the fly is made of "70D Nylon Taffeta 1500mm PU/SIL". Any thoughts on the best way to firmly reattach the hooks, or, more accurately, the fabric that the hooks are connected to, to such a material?
