lol, talk about an old thread resurrected! Looks like someone might actually be using the search tool!
Anyway, using ARO is only part of the after run procedure; you also have to clean the oil/dirt mud off everything remotely close to the exhaust pipe.

Ahhh, I remember my one (and only) nitro truck. Spent more time prepping, getting started, tuning, and cleaning up after running than actually running. If I wanted to do that much cleaning, I would be a maid (which I'm not)... and no comments about linc in a french maid outfit!
