After having a wet passenger carpet and all manner of strange electrical malfunctions I looked for Odyssey Roof seam videos and found
which I followed to remove the roof rails and the covering strips. There was also this comment under that video:
there is a gap at the front of the channels where they join the windshield SO THAT water can drain. The leak issues on our Odysseys are mainly due to the seams leaking. Therefore, if the seams are sealed as per this video - and not utterly gooped up, which would lead to water pooling in the channels which is no good - then when it rains the water cannot penetrate the seams and will run out the front and back sides of the channel. Any blocking of the front and back will lead to water pooling, which is not good. So, make sure that gap at the front, where the windshield and roof join each other is not blocked with gunk.
The seam did not look too bad, but there was a lot of debris under the strips and the debris at the front was damp. I cleaned the seam area with Dawn Ultra followed by flushing with water, drying, and wiping with alcohol as recommended in another video. I bought a 10 ounce tube of white 3M 5200 “fast cure” marine adhesive/sealant to seal the roof seam. Oops! The 5200 directions say to use solvent like acetone to prepare the surface and DO NOT USE ALCIHOLS BECAUSE THEY PREVENT CURE. It also says it should be used within 24 hours of breaking the seal.
So...questions.
First is it OK to wipe the seam with acetone now? Can it damage the paint?
Second, is that really a drain at the front of the seam to let water run down under the windshield?
I ask because my problem was water in the passenger foot well and dampness at the fuse block and relays behind the side panel there, and that is the area I need to prevent water intrusion; I didn't have water anywhere else in the Ody.
Here is a photo of the gap at the front of the right side seam that I am asking about.
and this is the mess of debris that was under the strip
