My First Mopar- 1966 Barracuda project

Do you recall how much material it took to spray the entire interior floor pan by chance? I'm considering using Raptor liner on rearward portion of my interior (rear firewall, package tray, floor pan, etc). I may just buy the 1 gallon kit so I have extra for other stuff as well. It looks like great stuff!
1 gallon worked for me. I sprayed the underside, floor pans, inside firewall, cargo floor, and the rear tire well. I have to finish out the trunk area now that I fixed the trunk gutters/rear quarters and two bullet holes in the rear panel. I have one quart left to complete the job.

It’s held up really well for 3 years now on the underside of my ‘68 Firebird. Cures pretty hard. I masked off enough area to make sure I could spray enough areas to use the whole quart after mixing. I’m very pleased with it.
