I wish I had a tig welder but this the next best thing to fix wholes and cracks in aluminum. I've used these a few times with good success. They work because they have a lower melting point then aluminum. Aluminum is one of the more difficult metals to braze because the part can disintegrate before your eyes is you not paying attention to the heat.
