I'm on about year six with the ADCO. I have had to sew in a couple patches a year from where, wear, wind and sharp areas on the TT have made minor tears. The company did supply self adhesive patch material to me N/C. Apply that material on both sides of the tears and hand stitch in place when you take it off in the spring. Suggest Fireline 6# test (kevlar fishing line) Won't rot, strong as hell and can either be match sealed on the ends or use super glue to lock your stitching.
