nothing to look out for, just follow instructions. Take your time, you can do big patches in stages. No clamping required, however I use the occasional peg to keep things in place. If looks are important you can use needles to keep parts aligned and a tiny dab to seal the pinholes after (never tried that method though). A little bit goes a long way and you can even fix a wet wetsuit to be used the next day. Cressi glue is a very good product (have also tried sikaflex, neorez, aquaseal and sellys polyurethane glue). Sika and neorez won’t last, the rest was mint. Sellys was the cheapest and longest lasting, but haven’t seen it in years.
I use aqua-seal to make my gloves last significantly longer too.

Nice, good to hear! Thanks
