patching aluminum engine cover

1980 Evinrude 4 HP aluminum engine cover -- has several 3 inch by 2 inch chunks of aluminum surface area missing . I am trying to fashion repair patches . Any suggestions as to a suitable material that will bond to the aluminum and also withstand the rigors of the engine vibrations ? Bondo ? Epoxy ? Fiberglass?

Patching aluminum

Cut a thin piece of tin and put it on the inside of the hole. Then use a putty type metal repair. It hold it's shape when drying. Press the putty onto the tin and over the outside of the hole. When it drys you can sand it down and paint it. I use metal putty repair on plastic an aluminum and it works great. You can get it at any automotive supply store or hardware store.

I'm not sure if JB weld makes this product but if you ask the counter person they should be able to put on the right trac.
