What kind of sealant is needed for the roof?

[MuleHawk]

Looking over the camper I noticed I have some sealant separating at the roof line. Would dicor work or is there a special other kind I should apply? Looks like the previous owner did some work there too from the discoloration. I haven't had any leaks but obviously don't want to get to that point. Should I try to remove the old stuff before I apply anything new?

Also my propane compartment smells of propane almost constantly, I had my cylinders inspected in case of a leak but they are fine, is it just off gassing because of temperature and pressure changes or should I look into the camper piping for a leak? I can't smell it inside the camper however so that leads me to believe it is off gassing.


Thanks!

I called FWC and ordered a tube of sealant. I haven't done the caulking yet. I will check what brand and type when I get home. jd

Although I use 5200 or 4200 poly sealant on some stuff, I've used this for bigger areas, like around the roof vent etc. Resealed my buddy's TT roof 7-8 years ago, still no leaks since then. http://www.3m.com/3M/en_US/company-us/all-3m-products/~/3M-Polyurethane-Adhesive-Sealant-550-Fast-Cure?N=5002385+8709314+8709324+8710676+8710815+8711017+3293223616&rt=rud

Mulehawk,

Silaprene is the sealant that FWC uses for the perimeter roof edge. I purchase a tube from FWC.

This thread reminded me I had a hard time finding Silaprene and went with something else when I did my roof edges last summer.

The term 'Silaprene' confused me since the brand name is used on a whole range of adhesives and sealants made by Royal Adhesives.

Here's an old thread about it. Post 11 has photos of the one used by FWC at the time... "Silaprene HAPs Free Adhesive / Sealant" in a green cartridge. I assume that's the one still used today.

Here's a pdf of the manufacturer's brochure with further info.

Manufacturer's part number is 12381 (for white) according to the brochure (but that's not on the cartridge)

If internet searches are any indication, it's difficult to find locally but can be ordered from FWC.
