I used it to put some life back into my expensive running shoes and their still going after running several miles in them after the repair. The product has a very strong odor, so be sure to use it in a well ventilated area, I would strongly recommending doing any work outside, because the fumes will linger for several hours. The packaging states to allow up to 24-48 hours before use, so that is what I did and I placed some heavy weights on top of my shows to help maintain the two surfaces adhered while it dried, you could also use a large C-clamp or something else to keep the uneven surfaces stuck together.
