The most common VHB type that usually ships with dash cams is
#5952 (black). It comes is a wide variety of shapes, sizes and widths. (Check Amazon) As an aftermarket replacement product you can purchase it in rolls of various widths and lengths such as 1 inch or 3/4 inches wide and use two or more strips placed side by side and trimmed carefully to the size of your dash cam mount using a sharp scissors or craft knife. I used to purchase it in two inch wide rolls which is ideal for dash cam mounts but at least here in the USA it has become hard to find in that size. I did find it in a bigger roll on Amazon but it is fairly pricey in longer length rolls. Any of the #59 series should work. The difference is the thickness of the foam substrate, but 1.1mm is optimal.
