I know that walker acoustiseal used to not get rock hard but they don’t sell it. I want to be able to remove it if needed but still seal nicely.

Thanks

Why would you want to even possibly remove the exhaust sealant, once sealed? Asking for a friend.

If you want slip fit pipes to seal and yet be able to get them back apart later, use a band clamp rather than a traditional muffler clamp. The band clamp won’t leak and the pipes will come apart much easier in the future than other methods.
