From somebody that has patched a LOT of tires...DO NOT PATCH A SIDEWALL PUNCTURE! They aren't fixing it for liability reasons.
I had a guy come in with a sidewall puncture and he wanted a second opinion...freaking idiots!
It's not about simply selling tires, it's about the liability of that shop. If they patch it and then the patch doesn't hold in the sidewall it will blow out.
