We are installing some Orajet 3675 with Oraguard 290-F laminate on some van windows and was curious if we need to seal the edges. I have noticed that 3M offers edge sealing tape, but Oracal does not. Does the Oracal require the same edge sealing tape that 3M does? We will be doing the 4 side windows (2 windows on each side) and the back window. Any tips/tricks to the installation? Is the Orajet 3675 the best material to use? Any feedback is greatly appreciated.
