McGuiver jacuzzi fixing

We recently were given a jacuzzi. After filling it up we discovered that there was a leak somewhere in a corner of the jacuzzi. The jacuzzi box was made of a cedar wood. My husband took his multi tool and cut down three different seems of the cedar, removed the wood, used the multi tool again to cut out the styro foam. found the line that was leaking, patched it, used instant foam to refoam it. The next day he put the cedar back on with a small finished nailer and you can't even tell it ever happened. What a McGuiver guy my husband is.
