Barrier Bond - Rubberized Undercoating Sound Deadener Kit, 28oz 4-Pack, Black Spray, Vehicle Undercoating, with Spray Gun

Great product easy to use

This stuff works well and was surprisingly easy to apply. I did multiple coats on the bottom of a 1970 VW beetle chassis. The gun worked better than expected. You'll definitely wanna protect anything from overspray because this stuff is sticky. My only complaint, which is why it got four stars instead of five, is that there was more product leftover in the bottom of each can that the gun wouldn't shoot out then I would like to see for something that costs as much money as this does. I would say between the four cans there was probably at least 1/2 of cans worth of waste, and this stuff sets up quickly enough that you can't pour any remaining product into another can. But overall, I would certainly buy this product again.

Sprays well, covers very well. Have to be careful not to stay in one place to long. This kit did the whole car down to the drop. If you’re doing more than one coat you’re going to want 4 bottles per coat depending on the size of your vehicle. I did a chevelle. If it sticks to metal as well as it does skin should last a long time lol.

Strongly recommend this product. It's strong, easy applicable, don't chip, bonds extremely tight, dries fast. I bought a extra gallon just to make sure it was as thick and protected as I wanted it on my old Chevy frame and it's yet to let me down yet. Saved me a tone of money from going to a company that does this and I think camee out better since I spent the extra time on it making sure to hit ever crack and crevous.

Used to undercoat a VW bug. Haven't used this before but had great results. Evenly coats the surface with a uniform splatter coat. Just like what I expected. Maybe not as extreme in material height like my professional truck bed liner, but certainly feels like it's going to protect the metal and not going anywhere. Dried fairly quickly and worked as expected. Cleanup was not hard with lacquer thinner on/in the gun.

Overall, this worked mostly as expected, I was pleased with the result and I would use it again, but there are things to be aware of. The coverage isn't great. The instructions talk about 2-3 coats. Maybe if you're working on a very small project. I ended up buying a second kit so that I could do a second coat. Unfortunately, there is no economical way of buying more product without buying the kit, which gets you another gun. Although most of the gun seems to be fairly well made (out of metal), the trigger is flimsy plastic and frequently slips off of the activating plunger. Forget about trying to do it left-handed. The pressure gauge/regulator is worthless. It's essentially an on/off switch.

The best stuff I've ever used great stuff.

Not sure how this got the reviews that it did. Ordered it and the gun is not functioning, it splattered the product everywhere. Not sure if any actually got on the underside of the truck as it was everywhere. The product itself may be alright if the gun to apply it actually worked. The gymnastics to return it are about as bad, as it’s not a standard Amazon return. Definitely think twice about ordering it.
