Today I installed the aft baffles on the engine. I started by picking up some high temp RTV from AutoZone. The RTV is used to provided a cushion for the baffling where it will vibrate against the engine. I masked up the aft baffling, roughed it up with sandpaper, cleaned it, and then smeared RTV in the specified locations. This was then left to dry for a few hours.
Later in the day I installed the aft baffles, and looked to areas where it was rubbing against the case. I found a few locations, and marked them with a sharpie. Then I uninstalled it all, filed down the offending areas, and then reinstalled for (hopefully) the final time.
