Thanking an adjunct prof?

I'm graduating soon and I'm starting to think about writing thank-you cards for my professors (I've already done a couple).

My department only has one adjunct faculty member, who is part-time and teaches a couple of 200-level classes. I don't know him all that well because I haven't had him as an instructor for two years (I do still see him around the labs and we're friendly), but he was an early influence in my undergrad career because 1. I really enjoyed and learned a lot from his classes and 2. he was the first professor who really pushed me to succeed and taught me the vital skill of overcoming failure.

The process of applying to grad schools has really opened my eyes to how horribly adjunct professors are treated (and my school is known for having low faculty salaries in general) and yet he still cares so much about his students which is something I never really appreciated when I took his classes. (I don't think other students do either because many complain about how strict he is and hate his classes.) 

I really want to write him a thank-you note that's basically like "you're an awesome professor, and I know you don't get enough credit as an adjunct faculty member but you're a rockstar and thank you for all your hard work and everything you do."

But I dunno, is that weird or inappropriate? It's not like he's my mentor or anything, I just want to make sure he knows he's appreciated.

Send the letter, but emphasize his contributions and your appreciation. Omit the middle part. He isn't looking for sympathy. Better yet, tell him that you contacted the dean to express your appreciation for his instruction.
