I found patching marks to be more of an art than a science. It depends on EXACTLY what the mark is made of.


The best thing I found was a Zodiac kit for patching PVC inflatables

3m 5200 with nylon cloth over

Wind Shear

3m trim adhesive (known as gorilla snot by auto mechanics) Sometimes this works and sometimes it will not stick at all.

Plastic Weld Hot Glue Sticks (be careful not to melt the mark)

Keep trying until you find something that works and write that on the mark.
