Never seen or heard of that being done....really no idea how inert gas would effect it since any spray painting relies on the "atomization" of the spray when sprayed...which means when it hits the air it relies on the small particles transfered in the air to "activate" its curing proess...
I would think an inert gas would really put a hurtin on that ...
I could see maybe a coating that can be also rolled on..but..if i am correct,raptor liner is spray only..so i would wonder if it will work.
Only way to really know?...try a little test sample on something and let sit for a few days to see if it really effects the curing of it.
