Is it seam sealer under the side window frames

I have generally found Sikaflex and 3M products to be excellent.

I used 3M 8115 Auto Mix for the temporary repair of the mess a bodgey (so called show car panel specialist) contractor did to the roof of my first HX van. The product itself is not is not overly expensive for what it does, but cost doubles for a one off use because you have to buy the 3M caulking gun. (Which may come in handy one day down the track if you need to use another 3M dual mix product I suppose). 8115 Auto mix would certainly do the job on the bonnet, but I was interested in the suggestion of the Gyprock adhesive because of the way it was advised.

I Have to agree though eske33 and Dick 71 it makes much more sense to stay with auto specific products, but I dunno I wondered.

3M Dripcheck seems to be an an older product, I found it hard to use in cold temperatures and eventually went with Sikaflex as the seam sealant for the exterior seams. There are some previous threads on this that may be of interest;

But the rear panel to frame is a slightly different issue. I thought it was horsehair/ felt pads originally? But then they absorb water (as does dripcheck) - noted in threads above, with some humor, it is hygroscopic. I would imagine replacing the rear felts with compound is a reasonable modern solution, as I say I am considering rubber and glue for the rear frames myself, this is because one day in the future they will be easily removable and replaceable to check for rust underneath them. I'm still interested still to know if Holden had started using compound for this job by HZ, or if they stayed with fiber pads.

Blurbs on 8115 are available at the links below (for anyone it may assist), it's gooey stuff, sets hard and doesn't fill real easy, its designed to glue panels together, not fill large spaces between panels and the frame, but neither is Dripcheck.

Hygroscopic. Nice. Don't think I've heard that term since trade school.
