Review: I can't find this locally, so... - ... desertcart to the rescue. I am using this item as a gap filler in an automotive application where the black color makes the difference between obvious ugly and stealth gap filling. Worked fine and didn't stick out in my car gaps like the original color formula. Some tips for the fellow desertcartians that need to know... The nozzle pushes on one click, then... you screw it on about a full turn or so. I think a lot of frustration with this product is due to incorrect fastening of the nozzle; no one goes beyond the first click and then complains that the nozzle is flimsy. Once screwed on, it stays on well, and allows for decent control. Clean up on surfaces with spray brake cleaner worked okay. Wear nitrile gloves to avoid wasted time getting this stuff off your hands. Don't get it on your Sunday best; it won't come out. It's rather unbelievable that I can't get this at the local Home Depot, hardware store, and two farm and fleet type stores. This stuff is great and because it's black, even better for some uses. Review: It's not as easy to get off so just a few things to ... - I've had to insulate our Rubbermaid Shed that we purchased @ Lowes a few weeks ago. Although it was not necessary... I figured if I was going to keep expensive equipment in the shed... I'd want it to be protected from the elements. This did the job perfectly. It has rained a few times since applying this product and there's been no leaks whatsoever. Just a little warning... be careful on how much you apply. It expands a lot so a little goes a long way. Also... wear gloves!!!. If that stuff gets on your hands (like it did with me) It takes forever to get it off. I had to scrub a few days to get the stuff off. You'll also want to be careful of it falling on the floor. It's not as easy to get off so just a few things to keep in mind. ## Features - Great Stuff multipurpose Black is a ready-to-use, minimal expansion foam sealant that fills, seals and insulates gaps up to 3/4 inch - Expands to take the shape of gaps and cracks - Creates a long-lasting, airtight and water-resistant seal - Black in Color, naturally blending into surrounding environment - Formulated for both interior and exterior use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MEH89XY | | Best Sellers Rank | #28,889 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,232 in Hardware Sealers | | Brand | Great Stuff | | Brand Name | Great Stuff | | Color | Black | | Compatible Material | This Listing is for 1 Can | | Customer Reviews | 4.5 out of 5 stars 1,060 Reviews | | Global Trade Identification Number | 00041343011001 | | Included Components | 12 cans of foam, straw applicator | | Item Dimensions | 3 x 3 x 8 inches | | Item Form | Foam | | Item Type Name | Multipurpose Insulating Foam Sealant | | Item Weight | 12 ounces | | Item dimensions L x W x H | 3 x 3 x 8 inches | | Manufacturer | Dow Chemical | | Material | Polyurethane | | Material Type | Polyurethane | | Model | 99054816 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 99054816 | | Style | Multipurpose Insulating Foam Sealant | | Style Name | Multipurpose Insulating Foam Sealant | | UPC | 041343011001 | | Unit Count | 1 Count | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Great Stuff - **Item Weight:** 0.1 Pounds - **Item dimensions L x W x H:** 3 x 3 x 8 inches - **Material:** Polyurethane - **Style:** Multipurpose Insulating Foam Sealant ## Images ![Great Stuff 99054816 Multipurpose Insulating Foam Sealant, 12 oz, Black - Image 1](https://m.media-amazon.com/images/I/71argbqhX9L.jpg) ![Great Stuff 99054816 Multipurpose Insulating Foam Sealant, 12 oz, Black - Image 2](https://m.media-amazon.com/images/I/71fyBCJMS0L.jpg) ![Great Stuff 99054816 Multipurpose Insulating Foam Sealant, 12 oz, Black - Image 3](https://m.media-amazon.com/images/I/81Pu7Dth+fL.jpg) ![Great Stuff 99054816 Multipurpose Insulating Foam Sealant, 12 oz, Black - Image 4](https://m.media-amazon.com/images/I/91Pw6LMTxNL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Can this be used for chipmunk hole?** A: Yes, but the chipmunk really resisted.

Fill gaps, holes, and get stuff to adhere. Spray with a plan, and let it dry. Be patient. Cut the expansion with a saw blade or sharp knife. Its paintable and durable. Get creative. You'll surprise yourself. DO NOT TRY TO WORK THIS STUFF WHILE WET. FUTILE & MESSY. HARD TO CLEAN UP. Let it dry, then trim it into shape. ## Frequently Bought Together - Great Stuff 99054816 Black 12 oz Multipurpose Insulating Foam Sealant - SELSIL Aquarium Silicone Clear Sealant - High Elasticity, Safe for Fish, Silicone Polymer, Solvent-Free, Ozone-Resistant Silicone Sealant for Freshwater and Saltwater, Transparent 10.14 Fl oz, 1 Pack - SELSIL Aquarium Silicone Sealant Clear, High Elasticity, Safe for Fish, 100% Solvent Free, 100% Non-Toxic, Fresh and Saltwater, 10.14 Fl oz.
