Here's how to patch a wetsuit.
A friend gave me this nice orange survival suit.
A coastguard station near her house threw it out because a mouse gnawed a hole in it.
They wrote "Condemned" on it which makes it extra stylish.
Here's the hole in the ankle of the suit.
I guess I'm supposed to buy eggs.
Step 1: Clean the Wound
Pick which side the patch will go on.
Cut that top surface away with the cloth layer (if any) away so it tapers down to the hole.
Here I'm using the scissors on the "instructables" leatherman ewilhelm laser-etched for me.
Wetsuits are made of neoprene rubber foam. The little bubbles in the rubber foam make it a good insulator. The bubbles are not connected to each other so it doesn't soak up water.
Old-style wetsuit material like this has thin knitted nylon cloth laminated on both sides.
It's a lot more durable than the newer suits with cloth on one or neither side.
It's also heavier, less elastic, and less warm because the outside cloth stays wet when you
get out of the water, and then your body heat has to evaporate this water.
Modern suits are a compromise between durability, elasticity, and warmth.
Most of the world's wetsuit material comes from a single factory in Thailand.
