LCR leaking through C Pillar join

[Tris179]

Evening Guys

I have been trying to find a leak in my boot and have narrowed it down to a crack in the join in at the end of the gutter after a few hours with the hose. It is at where the roof meets the C Pillar.

What is the best approach to fixing this? Just putting some sealant or Car bond on top of it?

I was thinking of grinding some of it away using a dremel for better adhesion?

Thanks

I had the same issue. You should be able to scrape out the existing cracked sealant and then reseal it. I put a photo on the forum a while ago of my one with the sealant removed -

I used some Tiger seal sealant and it has been perfect since.

Normal bathroom sealant doesn't stick very well to metal, found that out using it on door seals.
You're best using butyl tape or builders mastic.

I wouldn't go removing any paint it'll likely start rusting, just make sure the area is clean and dry.
You could even use something like black chassis paint.

Tiger seal works very well just clean the area really well and it will stick like no tomorrow
