How to Restore 1965 Chevrolet Impala SS Aluminum Cove Mouldings
Occasionally, aluminum parts are polished too aggressively, resulting in burn through, as is the case with these 1965 Impala SS Cove mouldings. To repair this damaged aluminum Impala moulding, grab a kit of Super Alloy 1 low temperature solder and flux and a propane torch.
An important first step to restore an aluminum Impala moulding is to pre-clean the parent metal. Super Alloy 1 is specially formulated to bond directly to bare metal, so pre-cleaning is necessary to ensure proper bonding of the filler rod. Simply use a Dremel tool, sandpaper or other abrasive to gently remove any impurities just prior to beginning your Impala moulding repair.
One the parent metal has been prepared, dip the rod into the flux and gently but quickly heat the parent metal. Note: watch the flux. When the flux changes color to root beer brown, this is an indication that the parent metal is at the proper working temperature of 350°F.
Next, to restore the Impala moulding, gently paint the filler rod over and across the hole. Notice the vertical position of the repair–customers often ask if this technique can be used with Super Alloy 1. The answer is, of course, yes.
To finish the part, smooth out the solder with wood prior to sanding or grinding. Additional flux may be applied to increase the flow and flatten out the finished solder.
After completing the repair, allow the Impala moulding to cool naturally, then remove any residual flux with a wire brush and warm water. That’s it. Now anyone can restore their own Impala moulding with Super Alloy 1.
Normally, you would not heat the flux or work area directly, but thin pieces quickly reach the 350 degrees F working temperature, so we opted for direct heating on this piece.
