Works good. Too good. If you’re not a pro, you’ll mess it all up. The headliner is up in the beater. But YouTube lied about how easy it is to use this stuff. Very sticky!! Easy to use. Easy to wrinkle the headliner too and just wad it all up. But oh well. It’s a beater. Nuff said.

Just get the Permatex for a better "spray on", both cans I bought required way too much effort in shaking between spraying. I did shake the can well before use.

Best choice! Absolutely necessary for anything above basic stock bass.
Bonded to services well, completely removed panel reverberation in my tacoma. Also really made the doors so much quieter even when closing. Very happy with the result.
Used only one set on my 01 tacoma 4 door. Installed inside doors on exterior skin panel, over interior door panel access holes (sealing the door to provide backpressure to door speakers (left drains open)), roof panel, and back wall of cab. Achieved about 70% coverage and am very happy.
2 8in SKAR SVR8 at 1oh on walmart power acustic 2500 (only rated to ~800rms at 2oh, forum showed testing at 1oh worked about 1kw) in 6th order with blow through into cab. With cab gain, im over 130db between ~30 and ~50hz. This was a necessary addition!
