Works
I used this to install 1/8th inch screening over my 1/4 inch crawlspace vents. This is recommended to keep embers from wildfire from getting into your crawlspace and setting your house on fire.

Hard to Apply
This stuff is really thick and not easy to spread. We went through a ton of gloves finishing our project. We needed it for our firewall to pass inspection and it did do the job.
