I hosted an example picture and excerpt from manual to help explain the job: https://imgur.com/a/Dqyyx

I'm reading the service manual page in regards to roof side molding, I'm assuming this is what I need to do to repair a leaky body seam/pinch weld responsible for water ingress that I tracked down with hose.

I'd like to do this job with dealership level or above quality and have found conflicting info online compared to the manual.

Some stuff I read just says clean the area and apply flowable silicone. Is this the "right" way it should be done or just a fast but bad alternative?

The manual talks about cleaning area, applying Primer "M" (which I found isn't available in the US). Then you use toyota lex-seal PN: 08850-00801 adhesive in the two spots front and rear and reinstall the moulding.

Lastly, I read that sometimes the crack travels further down the roof to the upper trunk. How would that properly be addressed?

Forget the web with this stuff it has to be inspected in person by a professional auto body shop for how bad this really is. What you may see isn't the story it's what you DON'T see is. That leak may have invaded feet away from the spot seen will not be clear until that molding is removed AYOR that it even can go back on without a horror show of work but you need to know so you can decide what to do.


If you want it done properly only the pro shops with that request can give you an idea of the costs and materials it will need. It does NOT have to be a dealer but you can request OE parts as needed vs cheaper or used as available is unknown till you know what it will take. May want to check the other side and see if this is too far along overall or picked on just that side for a reason?
