It can be used in areas such as posts, pillars, sills, doors, floor pans, roof bows, and various other automotive body cavities to prevent panel flutter and provide rigidity. The foam's expanding properties help fill hard-to-reach cavities. Once in place, it expands to ten times its original size, so only a small amount is needed to fill large areas. It is designed to mimic the appearance and performance of OEM foam products. The foam is compatible with a range of manual and pneumatic 3M applicators like the 3M Automix Applicator Gun. 3M Rigid Pillar Foam 08458 is the perfect OEM alternative to closely restore vehicles to pre-accident condition.

The fom is very rigid. Works excellent. It takes a few days for the foam to fully harden.

Worked good on my 71 dodge dart roof support. Made my own adapter for use in regular caulking gun.

It worked as advertised, but for the price it didn't go very far.

Very runny and takes a while to firm up. I used under van to plug thru-holes I had cut for wires. Drips everywhere and is HARD to clean up... I had some of that stuff in my hair for weeks. I can see it being great on horizontal and right side up surfaces.

I think I read it before I bought it expanded slowly and so some got wasted - I should have made application and let it finish expanding and use a new mixture tube for reapplying the next day

Used inside a vehicle pillar to attempt and prevent body panel creaking. Mix does not adhere well to vertical surfaces. Most of it immediately ran down to the base of the vehicle. Not much inside for the price. Will try a single component can style next time.
