The 3M08609 is an excellent repair. There are "if's" and "but's". The fold in the canvas must be good, and the 3M product will not hold if the fold comes loose. Make sure the fold is in place and glued good. Mine came loose and I tried several things to glue it. The only thing I found that would hold it was "Rhino Glue". Once I got the fold glued in place the 3M held it very well. I did this last summer and it it still good and very tight.
