Hi guys. Glad you all are benefiting from this easy fix! The longevity of the fix will depend a lot on the re-soldering quality. The semiconductors get really hot, and the legs will re-open again if not soldered carefully. One good solution to add life to any FSR is to have the blower running "halfway up" or more. The FSR block is cooled by air running over it, when your climate control fan speed is slow, the FSR block will tend to get hot.
If you want to use a solder with a higher melting point (Silver Solder) that's OK too. Lead free has a higher melting point also, but a little tougher to flow.
