Many online stores sell "wetsuit repair" products. Professional quality repairs that will last require experience, the proper adhesives, and heavy duty nylon thread used with industrial power  machines. Over the counter neoprene repair products often do not form a permanent bond and silcone based adhesives can even ruin your rubber! Seams simply glued back together, will not hold, and seam tape ironed on over glued seams will often melt the glue, resulting in a repeat of seam failure.
