Just bough a used Airstream and it has a slight leak by the skylight. Is there a special type of caulking I need to use to repair it?
What kind of skylight is it?
The reason I ask is that metal to metal sealants like Vulkem don't work that well on glass to metal or plastic to metal. If it's metal to metal, I use Vulkem 116 gray from Home Depot or Lowes. It's also used to seal concrete cracks.
If it's glass to metal, or plastic to metal, I use 100% pure silicone.
