sewer pipe/belly pan caulk

[crispyboy]

I would like to know about the caulking found around the sewer pipe and on the seams of the belly pan. It seems like it was originally white and still pliable.
I need to seal the area around the sewer pipe.
Any ideas on where to find this stuff?

Use Vulkem sealer.

A few Airstream dealers sell it.

That original stuff looks like butyl tape - sold at most RV dealers. It was used on ours around any of the pipe openings, etc. on the belly.....

Thanks - I do have some Vulkem I can try out. It just seems like this stuff was tougher than your typical butyl tape - looks like it was applied with a caulking gun.

You can still buy butyl caulk - it's generally used for flashing. Airstream may have actually used it in that form. The vulkem Andy recommends should work. I never thought of using it personally - just went back with what was on there.
