This forum is really a great place to learn new vocabulary!

I had never heard or thought about "aircraft detailing".

I only knew words like: auto-detailer, car detailing. auto detailing, etc.

I just google and I found lot of relevant words, such as:

aircraft detailer jobs

aircraft detail training

airplane detailing

I bet aircraft detailing it is a great job that gives a great sense satisfaction, and I guess it pays well too.
