I wanted to make a little art piece for my wife and utilized some horseshoes to make hearts conjoined.
The wife loved it.
A more pragmatic project was an unexpected stainless steel repair on a boat fin.
I used Multiplaz for repair of a stainless steel boat fin. It worked out great, if I could not have repaired it with Multiplaz I would have had to wait a few days for a professional to do the repair.
