Review: Great product, came recommended and worked perfectly for Ford Explorer leaky rear hatch hinge seals - Worked great for my leaky rear hatch hinge seals that had broken down over time on my 2013 Ford Explorer. I had water coming in and was pooling down into my spare tire area. YAY YouTube as I found an auto body repairman who did this exact fix and recommended this product. Followed instructions to remove decayed original sealant, cleaned the area, sanded to scuff for proper adhesion to bare metal underneath, then cleaned again to remove any debris and applied sealant. We'll see how she holds up. Repairman on YT says his he does lasts years, as he does this often on these vehicles... I sure am hoping so!!! Luckily it's in an inconspicuous spot so it didn't have to be pretty, but the color matching was def a plus. Saves me so much money by doing it myself, esp as a single girl holding up my household alone in this economy! Happy Dance!!! Product worked perfectly during loading of caulk gun and application. Mine came with the nozzle as some mentioned theirs did not. Tube did have a couple minor dings at the push/butt end but did not deter usage, so no deduction of stars for this. Higly recommend so far. Will update review after a good rain to advise how it does - if I remember to... LOL!!

## Questions & Answers

**Q: Does it come with the plastic nozzle?**
A: No! I ordered 3 tubes and no nozzle. I wish I’d have known that before ordering.

**Q: Can you sand it?**
A: Thank you for your question. We like to know more details regarding your application. When sanding is involved this imposes possibility of exposed metal causing corrosion/rust.  Please contact us at 877-666-2277 option 2 to discuss your application.

**Q: What chemical can be used on it to “smooth” after applying?**
A: Thank you for your question! You can tool the 3M 08367 Urethane Seam Sealer with water or mild solvent such as a pre-cleaner. Do not tool with any alcohol containing solvents, they will stop the curing process of the seam sealer.

**Q: Is the tube made of plastic or thin steel ?**
A: Thank you for your question! The 3M 08367 Urethane Seam Sealer is packaged in a thin metal cartridge.
