Around July of 2007, I noticed that my 3-year-old wetsuit had developed a small tear at the bottom edge of one of the legs. Over the next few months this tear expanded until I had a sizable rent in the suit of about 3 inches. Since there was nothing wrong with the rest of the suit, I opted to try to repair it myself. I found and followed these instructions from the eHow website on this topic:
Things You’ll Need:
* Neoprene Cement (I used Aquaseal)
* Heavy Sewing Needle
* Strong Thread Or Dental Floss
Large rips, or rips along seams, need to be sewn closed. Use strong thread or dental floss and a heavy sewing needle. Hold the two sides of the rip together and use a spiraling stitch to sew them together.
Coat both sides of the newly sewn rip with neoprene cement to make it watertight. Neoprene cement can be purchased at surf and dive shops.
Small cuts and rips can be sealed using only neoprene cement. Hold the rip together and coat with cement. Apply to both sides. Let dry for 10 minutes and apply a second coat.
