Sealant for roof vents & skylight?

[Dodge Man]

I have had my Safari for three years now and the sealant/caulk around the roof vents, skylight, tank vents, etc, on the roof is shot. I looked through the forums but could not find an answer to my question. After I remove the old sealant around everything, what should I use to re-seal them with. From my local Airstream dealer I have gotten two answers. One guy said use Parr parlastic caulk, another guy said use Dico, or is it Dicor, self leveling sealant. Also I read somewhere on line to use Sikaflex721. The sealant/caulk that is there now is from the factory and it appears all they did was smear it up the sides and out from each part on the roof. Any help/advise on this would be greatly appreciated.

You can use Vulkem, which is slow setting, like a couple of days, or you can use Sikoflex, which sets up in a couple of hours.

Roof Sealants,

If you take a look at the Airstream Store website you will see they sell both the Silkflex721 and Parlastic. During a recent visit to Jackson Center I also noticed that some of the technicians were using Bostik 1100 on the roof. All of the above will work fine, since you will probably be replacing in another five years.

Thank you both for your answers.

Do not use Dicor, IMHO. It will turn yellow in a few years and look like hell. Ask me how I know.

I wish I would have checked out this forum sooner as I've already started to gut my 75 Argosy and have tons of questions. I removed the ugly old antenna leaving a few holes. I patched it with ProFlex. After letting it dry I applied an aluminum patch (Airstream guys gave it to me) I used more ProFlex between the 2 pieces of aluminum and put it together with Airstream rivets. I have also removed the putty around the vents and was planning to use mobile home putty tape to reseal it. So tell me have I made a mistake yet and should I go with the putty or one of the products mentioned in this thread? I'm doing what the Airstream repair guys suggested.

I would use Vulkem or Trempro which is almost the same. Sikaflex is good too. G
