## Questions & Answers

**Q: How to use when installing windshield? Older Vw with rubber seal. Thanks**
A: Not sure on VW, but I used this on a classic Mustang between gasket and car windshield frame ONLY. I used urethane between glass and gasket,  NOT this (08509). This will NOT set up and should stay tacky for a long time. I used urethane to make a seal between the glass and gasket.

**Q: I need to replace the vapor barrier on my car door, is this suitable for that purpose?  I am concerned about any odor associated with it.**
A: 3m 8509 is what's recommended to be used for this purpose on older vehicles (my 68 mustang), so i see no reason why it wouldn't be the ideal thing to use with any other year vehicles. the vapor barrier on mine is wax paper (if that matters)..

**Q: What is the minimum temperature to process this kit?**
A: I used it on a beautiful summer day, so I cannot help beyond telling you I used it to seal around the windshield on my 1966 Mustang.  I just went out into my 30-degree garage and I can still make fingernail marks in it.  I would assume if you started with a room-temperature tube (so it would come out of the tube easily), you could apply it in a location with a much lower temperature (like my garage).

**Q: How long should I wait to put chrome window trim back on**
A: This product stays flexible and does not harden so y o u can apply any molding when ever your done with the task .

## Customer Reviews

### ⭐⭐⭐⭐⭐ caulking
*by J***P on June 5, 2025*

did great the job needed

### ⭐⭐⭐⭐⭐ Stops windshield leaks.
*by B***P on July 5, 2022*

1960's fords, maybe other manufacturers, used a rubber gasket with this bedding compound to seal against leaks. This 3m product is non hardening and can be cleaned off with mineral spirits without hurting your paint. If your initial installation still leaves leaks, you can peel back the rubber and squeeze more in (both inside and out). As a final measure you fill in the Crack where the stainless meets the body. Clean up with mineral spirits.

### ⭐⭐⭐⭐ Pure goo
*by J***N on February 7, 2016*

This is the gooiest stuff you can possibly imagine.It's what one might use to train hazmat staff on contamination containment.Any contact transfers the goo to something else, which then transfers to something else, all the while spinning off fine black strings like melted cheese out of some dark nightmare.It forces you to think ahead about clean up procedures and supplies.Keep away from fabrics, headliner, anything that can't be cleaned up with solvents.After a couple weeks out of the tube, it seems to firm up to "tacky".A "firmer" choice straight out-of-the-tube might be Sikaflex 220+, which I have also used.
