Homemade motor mount inserts

[Thunderskull]

I kept seeing that folks were using window weld as a material to create a solid motor mount. I'd always though about doing it and actually bought a prothane insert for the front mount which I like very much. One day I was walking in home depot for an adhesive to keep the door moldings on and saw Polyurethane Premium by PL. I used it for the door moldings and it worked REAL well. I couldn't pull those things off without a crowbar. I thought I'd try to use this stuff for my motor mounts. I did the rear one and the driver's side mount. The stuff takes a few days to harden, but it works really well. There isn't much in the way of give in the motor mount so if you're looking to go REALLY solid, this is the way to go. It bonded to the rubber very well. There is a bit of vibration when you're done but you get used to it. Besides, I kinda like it. The price was good too since it was like $2 for a tube. 1 tube can do all of your mounts.

Sounds good, but I dunno if I could have my car sit for a few days waiting for them to harden. I thought they were quicker than that, are some brands different or something?

Well, I made the mistake of doing it all at once instead of a little at a time. The thicker you apply it, the longer it takes to harden all the way through. I did it on a Sunday and they weren't ready to go back into the car till Tuesday. Though that time could probably be hastened if you bake em in the oven at about 150-200 degrees.
