I'm no expert at this, but I think after that it should be fine. If I were going to do the inside of the barrel, I'd probably take a sander or angle grinder to it after a wash and rinse, just for reassurance, if anything else.
I'm curious how it works out for you, though. If your red liner is as horrible everyone makes it seem, then a couple of cans would be worth the risk if you're unable to do a long, hot burnout.
