Default Joint seal

Hi All,

I have a question about how to seal the joint between the back of the cowling and the body panel below the front windshield? There is what appears to be some kind of joint filler in there, but it's dried up and allowing moisture to leak into the truck (noticed it in the glovebox and passenger floor board).

Thanks!

I've heard of people using 3m drip check successfully for that seam but I have not used it myself.

Should I remove the old material first or just apply over it?

3M seam sealer. To answer your question directly, remove all traces of the original seam sealer and apply to clean painted metal or bare clean metal. It's all in the prep.

What would be the cons to just welding it?

For starters, never being able to fold down the windshield as Mr. Toyoda intended.

Like he said. Plus welding sheet metal is not for the faint hearted and still requires filler in most cases.

that shouldn't affect the windshield folding, it's well below where the w/s folds

but as mentioned, welding sheetmetal is not easy....burn through, warping among are the most common problems
