Bob where is the picture???!!!!
Ditto on superiority of Gorilla tape. I also use Gorilla glue, what is good if you are not in hurry as it takes few hr to set and expands in the process.
Lately I was restoring my canoe and was spraying new gellcoat.
Having few repairs on camper cap and fiberglass, I sprayed them over as well.
The spray made the repairs invisible and gellcoat adds strength to the repair.
Time will tell how strong it is, but cosmetically it is perfect.
White gellcoat covered my dark green canoe in single coat btw
