Meet Brian. He is a viewer just like you who used my videos to restore a 1959 Aljo Canned Ham Trailer and is now getting ready for paint. Brian stopped by my place on the way to the painter's to show me a problem he had with the metal skin on the front by the tongue. This problem of buckling is one that has come up before and now we know what causes it. Unfortunately I think there is too much damage to the metal to repair it properly so even after we fix the problem it will still need a gravel guard to hide the kinks. But if you plan on using your trailer a lot then there is nothing wrong with a gravel guard anyway.
