It works well for do-it-yourself repairs on cast or extruded aluminum used on vintage travel trailers. When you are finished, you'll have a repair that is stronger than the aluminum and even harder than mild steel.
We've seen it used on door hinges and to repair aluminum window frame corners, but it would work great on other hardware like marine propellers, engine castings, tools, and carburetor bowls.
Excellent corrosion resistance. Working thickness from 1/32" up to 3/8".
