How do you patch holes in aluminum?
I need to patch several holes about the size of the head of a screw and one hole that is about the size of a half dollar coin.
I have no welding tools, I just need a simple and easy way to patch these holes.
What can I do?

Probably not the best way, but the small ones could be patched with a dab of aluminum colored silicone, and the large one (not really large enough for screws arond the patch) could be patched with a small piece of aluminum glued on with silicone.

Could I use bondo?
Any more suggestions?

countersunk rivits for the small holes- How visible is the large hole?

JB weld epoxy , same color, can be sanded smooth,

Or you could buy another sheet of aluminum.

Have a good day.

Naw, go with the JB weld epoxy.
