My first DN Tech Talk was about shimming runners. I used 2 different double sided tapes. One of them was very special because of thickness. I received a lot of questions about what type of tape it was and I was not able to answer them because simply it was not written. Now I had to reorder this product again and the name is there!!! The magic product is 3M 467MP. If fact it is not double sided tape because double sided tape is core material covered with ahesive film on both sides. 467MP is adhesive film, no core. Therefore it is 0.05mm in thickness only!
