I have a 14' am luminous that's met a few rocks. It's older and it leaks through some of the rivets in the middle. Does anyone have a fix for this ?

A friend of mine kept a 16' jon floating for over 20 years with JB Weld.  Once you put it on a clean spot and let it setup for 24 hours it is apt to stay on forever.

Try re-bucking the rivets if they are easily accessible.  The tools to do it are cheap and it is a permanent fix versus a patch.

That's not an option. There is decking built on top of where the leak is. I think JB is my best bet. Now I just have to wait for a nice, warm day.

There are much better products than JBWeld for this type repair.  Go over to Tinboats.net and search or ask and you will get many answers.  I have used and keep on hand some Locktite epoxy than is specifically for aluminum boats and is water proof.  It can even be applied in the water.  Loctite Marine Epoxy and it can usually be found at Home Depot or Lowes. Here is another good product in this video as an example.
