Heat Freeze Heat Sink Stops Warpage on VW Door Panel Repairs

When brazing, soldering, or welding near heat-sensitive materials, protecting surrounding components can be difficult. Without a heat sink, the only option may be time-consuming and costly disassembly to prevent heat damage. Heat Freeze Heat Absorption Paste can act as an effective heat sink by drawing heat away from surrounding areas during metal repair.

In this video, we return to Resurrection Auto Body in Olympia, WA where Jim demonstrates a heat sink how to example while repairing holes in thin door panels of a Volkswagen Bug using TIG welding.

To compare results, Jim applied Heat Freeze around one steel door panel hole and left a second hole unprotected. Both areas were TIG welded under similar conditions. After welding, Jim showed that the area protected with the heat sink paste had a smaller heat-affected zone, even though that hole was larger than the unprotected pinhole. The protected panel also showed less warpage.

Troubleshooting Tip:

During one weld, the heat sink paste was placed too close to the weld area. Because it pulled too much heat away, the weld did not properly form. The fix was simple: the paste was removed and repositioned further from the weld area before continuing.

After completing the door panel repair, allow the weld to cool naturally, then remove Heat Freeze and return it to the jar. If Heat Freeze begins to dry out, add more water and mix it to rehydrate the all-natural heat absorption putty. (Use gloves when touching Heat Freeze directly)

For this application, Heat Freeze concentrated the heat of the TIG welder, allowing for less warpage and heat affected area and a cleaner finished product.
