china wall sealant??

You have to be careful where you use that stuff. The lid to my sheet metal cross-ram is sealed with that stuff. I spent hours trying to remove the lid....with zero success. I don't think it needs the bolts.

I use black RTV, the store brand. I don't use the right stuff, because I want to get the intake back off without breaking it.

This is why I like Black Permatex. Right stuff can be too good in some applications.
