First of all, I fully admit that I have no idea what I'm doing~

Secondly, from doing ghetto home repairs, it seems to me that fully cured polyurethane sealants would be quite stiff. So while I certainly want the engine to stay put during hard accelerations, I am not trying to turn my shxtbox into full racecar mode, so I didn't feel comfortable with polyurethane.

Thirdly, since the mounts are gonna be sitting right next to the engine block, I figured whatever "stuff" I end up using is going to need to be capable of handling that heat. The high temp RTV silicone that I bought was advertised to be capable of handling up to 246°C, so I thought that might be appropriate.

I'll keep polyurethane in mind if I ever end up doing something similar again. In the mean time, I hope that RTV silicone would still work sufficiently well...
