I don't get why people struggle with non air egress for something like this.
Can it be done, sure - but your time wasted doing it will negate any savings on material.
We do a lot of striping for our municipality - 3 colors, 1 Reflective 2 non - They specced permanent, non air egress for the 2 colors because its what another sign shop used - We brought in 5 rolls of each color because we had hundreds of vehicles to do. We ended up using 1 roll, finding out they had an air egress version... Which was removable and saved the company tons of money when they retire the vehicle, So we bought a roll and our install time was almost halved. We still have 4 rolls of each color from 3 years ago... We only use it if we have supply issues, or for smaller items like numbers. I'd rather throw them away then try to do a corrugated trailer with them, that was a pain!
Look for 2080, or Avery SW9000 films and use that. It's a bit more expensive, but you'll save yourself a lot of effort and cussing trying to install non bubble free.
And don't get me wrong - it's still good to learn how to install non bubble free, because its not always available.... it's a good skill to have. But if you spend 20% more on a roll of vinyl, and it frees up you / your installer to do 1 extra vehicle throughout that whole roll of vinyl, you've made your money back.
