Bongo Fury

My aft is making a farty noise when it goes up and down....I think it could do with a bit of a lube Could anybody tell me which is the best stuff to use I have a few types of wet and dry lube for the bikes in the garage, but dont want to risk making a mess of the top when the material folds in past the rail.
Assistance greatly appreciated.

Thanks

David.

Crisp & Dry in a spray, squirted on the rams & runners seems to do the trick.

ditto above mine used to sound like a pig farting = OK now!!!!

I used http://www.richardsonsonline.co.uk/acc_ ... be%20400ml BUT only on the runners not the rams, the plastic guide wheels were dry on mine..........
