I got my Napa Sil-Glyde from NAPA at the local NAPA store. The original Multi-Purpose Sil-Glyde is made by AGS. Though both are silicone, not all silicone greases are made the same nor do they have same specs and operating characteristics.
AGS Sil-Glyde at Amazon is $9.39. It is moisture-proof and heat resistant to over 425 degrees F (218 degrees C),
NAPA Sil-Glyde at NAPAonline is $13.49. Comment: This is the silicone lube you want to use solely on caliper pins. Safe around rubber boots or any rubber brake components. Also rated at a higher temp (-20 To 500 Deg. F.) than the original AGS formula.
