I'm getting ready to install some roof rack tracks. I'm not sure if butyl tape is the best seal. I think I would get a better seal with a thick bead of 3m sealant 4200 with a dab for each roof screw. Of course this just my opinion. Other who have install roof rack tracks, what did you use? Sealant or Butyl tape?Fyreman said:When you install the tracks make sure to put Butyl tape under the track to seal it up. I was recently talking to Stan Kennedy and that is what he recommend to me.
I don't know about the butyl tape, but Terry Bud told me FWC uses Silaprene sealant as you described. I removed my end caps to add landing pads and put a dab on each screw and a bead around the cap to reinstall them.super doody said:I'm getting ready to install some roof rack tracks.

The tube I bought from FWC was white.super doody said:JHa6av8r,
Do you happen to know what color Silaprene is?
Yakima's longest bar is 78". FWC should be able to give you the measurements to make sure you attach the tracks above a roof rib. A call to FWC could also get the pros & cons of why they chose the tracks instead of a gutter mount.mountainsun said:I'm close to mounting a roof rack to my camper, and looking at different options. It seems most racks are mounted onto the roof and the 4 points of roof penetration are determined by the width of the bars.
I'm a little leery of puncturing the roof.
I'm curios why more people have not gone with the gutter mount rack system?
I can find the correct diameter round pipe in any length and create my own crossbars, in this case 77" is the width.
I believe the widest yakima bar is 72", and not sure about Thule.
Anyone else go this route? Looking for any reasons against going with the gutter mounting.
Thanks
78" is a standard size Yakima bar., and I think the ones FWC supplies if you order the complete rack They also sell 86" bars, but of a larger dimension due to the length.Wandering Sagebrush said:I have 78" bars from days gone by, but I am not sure if they are still made. If you want something bigger than 72", contact Yakima directly, or check places like Rack Attack and ReRack for used gear.
