anti whistle trim for roof bars

[chunkolini]

I bought some cheap roofbars. they are covered with slippery plastic trim not clever for carrying kayaks in the rain.
They were supplied with a length of 'anti whistle strip' to fit into a channel across the bottom of the bars. (They seem to be folded up from flat strip into a box section) it keeps the noise down, but if I remove the whole of the plastic over it will leave most of the channel open and leaves me with what sounds like a harmonica orchestra on my roof. The antiwhistle thingy was I think a sort of 'H' shaped rubber strip to fill a gap of about 3mm. Has anybody got a clue where I can source a couple of M of this stuff.
Ive fabbed up a larger roof rack that sits on top of the bars and works a treat but is a faff to remove and replace with the plastic coating on the original bars.
Plan A is to fit anti whistle thingy over the gap and use my extension as and when I need it.

You can buy various types for Thule (alloy) roof bars but it is expensive for what it is:

.... thinking about it - the gap on the Thule bars is more than 3mm.

When I did a lot of kayaking I just taped or cable tied pipe insulation to the roof bars. I made uprights to go onto the bars so that the kayak(s) would sit on edge supported by the upright - no slipping with this system. For more delicate racing kayaks I used V bars.

Can't help with @chunkolini 's problem, but I came across this design and fell in love with it a while back while investigating making/buying () a roof rack for my Nissan NV200:

It's looking like a Christmas/New Year project to fab it up and fit it in place of the existing roof bars, and I'm thinking of fitting a pair of removable box section "H" frames for carrying my Grumman canoe. I appreciate that it won't be to everyone's taste, but I love the look of it and with my Thule roofbox up there, it will keep the inside of the van tidy when I get away on diving/canoeing trips.

tidy, mine is a bit brutal but does the job.
I'll post photos tomorrow.
The price of that strip!!!there has to be a cheap bodgeworthy solution, Thinking cap is going on.
That strip must have another use somewhere, i cant see it being made in 30cm sections just for roofbars

Its just covering the hole........use some duct tape

Good quality gaffer tape or fill the gap with mastic.

Ive got VW roof bars.......horrendously expensive....and very specific....each corner is marked.........the rubber that fills the gap came seperately (no idea why) and you cut it yourself.......so I cut it exactly the length of the bar....wrong, because the locks dont fit when the rubber goes all the way to the end....a bit of a faff when the bars are over £200......but you go get a torque wrench to tighten them up
