Most places are ok with substitutions,not like they have much of a choice.
I believe 3m window perf has a really long warranty / estimated life compared to everyone else... So finding a comparable warranty would be hard... But I'm sure the other brands hold up just as well.
We use contravision performance a lot, it works great. I prefer to install it over 3m perf - the thick backer they came up with for latex printing makes installs quite a bit easier too.
We always let the government places know we're substituting.. 9/10 times they say they're not the professionals, and to use what you recommend.
However there's a few items that are specced and tested by engineers and they won't budge on replacements, because it'd cost them a ton of money re-testing. Unless they're putting some perf on an f150 though, I think you'd be fine.
