Lotsa times when I hear 'Aerospace', or the like, associated with plastic trim on a Jeep I assume there's a wish to connect the product to a high purpose or standard. Often times there is some ingredient that is beneficial but perhaps not deserving such lofty status.
I always like to look at the MSDS. Sadly, the Gvmt. allows people to shield their ingredients ...but they still have to list them. Here's the top one for 303:
Water — CAS:7732-18- 5 — 75% TO 100%
The next highest is a 'Proprietary' 0% TO 15%. Along with a few lesser % additives. (one was <1% ..another <.235%)
Of course, it's easy enough for their competitors to send it out for analysis - they know what's in there ...and likely, stock the shelves with a similar mix.
I would have wished the PO of my rig was as motivated to have wanted to use some of these things and the real magic: Concern w/elbow grease. It would have saved me a lot of work.
