So I replaced my fabric pop-top liner with a nice waterproof synthetic one. Fantastic except that unlike the old japara cotton original, which had all the draught-resistance of a tea strainer and just let the breeze into the beast, this one actually stops wind and at anything from 60km/h upwards, balloons inwards, inflating like a kiddy paddling pool. It's a Sopru, and obviously a bit gappy at the front/sides when clipped down.
Now, I've seen on a couple of US sites a version of the vinyl pinch-welting that lines the outer edge of the top, but incorporates a fat circular-section neoprene sealing lip around the inside. Apparently the Westfalias use 'em. Anybody seen anything like that from an Australian-based supplier?

If you have any of the old bit left rock on down to your nearest Clark rubber store.....

The JK stuff looks spot-on. Cheers for that!

AVD does it again !!

Splitbus - that seal from indrub.com is per metre.

JK price is for 7.5m (aparently the length required).
