Just curious if anyone has used "the Right Stuff" RTV on the exhaust of a motor. I put my adapter plates on last night, and without putting much thought into it that is what i used. I looked on permatex's website and they say its good for 450*F continous and 500*F spikes in temp. Should i go back and re-do it with copper RTV? That stuff is rated to 700*F on permatex's site fyi.
