I appreciate it John, but it's one of those things that after you've used something for so long with no issues, it's hard to change to something else.

I think the reason you found so much of it in radiators, pickups, etc., is because guys tend to just squirt out big blobs. My application of RTV is almost like a layer of paint....very thin.

The Right Stuff is probably a form of the stuff that Cat uses. I have heard that before. I use it on intake manifolds and you can pull all the bolts out, hook an engine hoist to the intake and pick the engine up off the ground. It also hardens very quickly so you can light an engine off pretty soon after you button it up.
