As a mechanical engineer, I use silicone grips in my work. Silicone grips provide excellent adhesion and durability, making them ideal for creating strong and reliable connections in my toys. I also prefer silicone grips because they are easy to clean and maintain, which is important in a high-traffic workshop like mine. In terms of grip primer, I use a high-quality silicone-based primer to ensure a secure and lasting grip between the toy and its accessories.
