Roof Leak T176 Spoiler Area?

Hey guys, I really need some help.  I have a leak near the spoiler on my 176T (this is the model that has the bed that folds out the back.  The spoiler is different than the spoilers I see on the other models.  The leak is coming out of the areas inside marked with the red arrows.  It does not appear to be going in to the wall, I can see no evidence of delamination or water issues in the outside walls of the Rpod.  It is landing on the floor in the RV where the red arrows show.  I sincerely thought it was coming from the seam where the spoiler meets the roof, but I have already used the Eternabond tape to seal that seam and it seems to have made no difference in the leak (see pictures).  Questions:

If you have a way to connect a blower to pressurize the inside of the RPods (all doors and windows shut except where you have the blower connected) then use a bubble solution on the outside to see where air is leaking. When I worked at a boat building plant, that is what was done to check for leaks around windows, hatches, etc. Think blower like those used to inflate bouncy castles, not a box fan. 

As you are displaying interest in the blower idea but are wondering about how to find leaks, I think it is time to share how we used to find pressurization issues/leaks on C130 aircraft back on the day. We would pressurize it while the aircraft was sitting on the ground. One of the other people on the troubleshooting crew would light up a cigarette. A slow stroll about the a/c while watching where the smoke stopped wafting about and made a bee line to where there was a leak (usually a window seal, and they were always miserable to pull, reinstall and reseal).

Now, an rpod isn't a sealed/pressurized aircraft but if you have a high volume blower, a sturdy sheet of plastic, some good tuck tape and a similar "smoke generator" it should show you where water could get in...you just have to get close to it. And this way you don't have to let water leak through while doing your search.

Really appreciate the help guys.  I ended up taking a garbage bag and some foil tape (used for sealing AC vents- very sticky and easy to tear) and taped off selective areas of the roof to find the leak.  I then used a hose and soaked it and eventually pinpointed the leak.  It was not coming from the area covered by the eternabond- so that seal does appear to be working.  It was coming from the area where the black screw cover meets the spoiler.  There is this little dome of black plastic that covers the screws that run the whole edge of the roof.  That area has a channel that allows any water that slips through to drain right near where the eternabond seal is at the spoiler seam.  The water was going down in to that channel, and there was a screw in there that was never sealed from the factory...  so it was dripping down in to the RV, then running down the wood post on the ceiling...  Sealed that up and stopped the leak.  I think it has been like that since it came from the factory...  so lame.  Anyway, hope anyone with this issue might find this breadcrumb trail and it ends up helping someone else...  Thanks again for the moral support and hints.
