Safe to carry in flight in check in bags?

Yes just put between your firearm and large lithium battery

I have a fiberglass body that I am spraying with raptor bedliner. Should I first use primer after sanding then grip?

I am not a body expert but I did my ARE fiberglass tonneau cover with the raptor on the exterior. I sanded with 120 discs and them wiped down with denatured alcohol. I did not have prep cleaner. Six months later it is still looking like I just sprayed it. I hope that helps. I'm sure the are body people who will say different.

Just curious if this is transparent? Gonna spray this over some plastic chrome

According to their MSDS, it's just solvents: toluene 40-63%, acetone5-23%, less than 5% xylene and ethylbenzene. Bulldog is made of much more.

Does help the paint adhere to plastic surfaces.

Worked well to help paid adhere to the plastic. Without this, paint would easily scratch off the surface. Sanding is critical as well as cleaning prior to painting, however this is another important step in prepping the surface.
