Herculiner aerosol was included in my protective-coating purchases.
The featured Amazon option is Herculiner Aerosol Spray Truck Bed Liner, 15 Ounce Spray Can, Black, Textured, Suitable For All Truck Beds, 6-7 sq ft Coverage.
Where it fits my build
While fitting the heater below the passenger seat, I worked underneath the van on the intake, exhaust, fuel filter and pump mounts. The black substance visible on the undercarriage was Fluid Film Black, which I had applied across the underbody while leaving the exhaust parts uncoated.
Much of that session was spent lying on my back. I recorded how cramped the space was and how tiring it became to hold my head up and work with both hands around the mounting points.

My build notes
The diary separates the coating already present beneath the van from the heater work happening that day. The photos are useful for seeing the available working space and the location of the lines and attachments.
The available space under the van affected the pace of each mounting task.
Alternative products
Two alternatives to compare
The featured Herculiner can and the RAPTOR and Rust-Oleum alternatives all use aerosol packaging. Each gives a different coating option in a compact spray-can format.
RAPTOR 1K Black Bedliner Aerosol
This RAPTOR 1K aerosol applies a black textured bedliner coating. The spray can provides a separate format from the larger mix-and-spray RAPTOR kits.
