What sealant should I use between AC gasket and roof?
I am installing a Penguin II low profile roof AC unit. What sealant do you recommend to fasten the gasket to the roof?

The trouble with using a sealant is that the gaskets are expendable- they will need replacing at some point. If the gasket is sealed to the roof, you've added a huge amount of time to the job- getting the roof clean and smooth.
This I learned, but the old gaskets did last 20 years before the refrigerant blew out......
Installed the new AC without sealant although I will not last as long as the old gaskets did.
