This baffle material is thick enough to handle the job in spite of being silicone. The 36 running foot was perfect for the peak crown of the cowling on my Mooney. The 3 roll wasnt quite tall enough.

It did not arrive at the expected time, so I got the tracking number and checked it out. I thought it was coming from Corona, but it came from Peachtree. It was put in the mail the day it was ordered, and looks like it just lingered in the Peachtree USPO for 5 or 6 days before heading my way. I did receive it a couple days ago, and it is already installed in the airplane.

The baffle seal material was just what I expected. It should last for years.

Nice stuff. Soft and flexible enough to bend where it needs to bend. Works well with aluminum rivets and washers.

The only problem with this product is that it is too short for the Cherokee plane it is listed for. These rolls should be 10 ft instead of 9
