Thread: Filling Motor Mounts

Is this stuff fine to fill my motor mounts?

3M 08690 Fast Cure Auto Glass Urethane,, 10.5 fl oz Cartridge, 12 per case

I have some of it laying around and i want to use it. Thanks.

i've used 3m window-weld. works pretty good for a mount fill. you will have to let it sit for about a week though to fully cure, which is the only catch.

whats does ths do ?

ive done my passanger side and driverside tranny mount.....ive got pics some where hold on.

heres my old thread...

Filling in the cavities in OEM mounts firm up the engine and tranny mounts. I've done it with little or no increase in vibration. Especially good for the firewall and dog bone (at the radiator) mounts. Leave the others alone or replace with OEM to avoid vibration. The Window Weld doesn't last forever and may need to be refreshed periodically.

I have been debating making some steel or aluminum mounts, I have prothanes now and I cant get enough of them =D

I used the 3m stuff before my prothanes. They were way better than the solid urethane mounts, but didn't control engine movement quite as well. Still I prefer it over the prothanes.

I only let mine dry for a day and bolted them in. Only did the front and rear. Amazing. You just have to make sure that the mount rubber is completely clean and free of dirt and debris, otherwise the urethane can have problems adhering to the rest of the mount.
