John, Thanks for your reply. I've read about the stick together ones, they don't have a high success rate. I've ordered a gaiter and cone kit which includes the clips and grease. They asked for make and model and cc of car, so maybe they are not ' one size fits all '. They say the rubber is high quality neoprene which sounds OK. Not sure if I'm allowed to mention the name. I'm waiting for the kit to arrive so will let you know how it goes.
