The factory used something with a fairly large nozzle as what was applied was quite viscous allowing a heavy build without too much sagging.
The inside of the quarters in the trunk have approx 3/16-1/4" build which can not be achieved using a spray can or even a schultz gun.
I bought a textured ceiling gun, with 3 different sized nozzles, to try to get a suitable build, haven't tried it yet, may be nothing but a mess.
