You did indeed, but my point was that you then also answered another question that had not been asked. I beg to differ. I had a minor leak and it did cure it. The van was still dry when sold some years later.

I'm in agreement with Angus in that I believe that the whole awning rail should be removed before using new sealant. It's not a major job and it will ensure that all traces of moisture and other dirt/contaminants are removed, If you took the time to read my response, Phoenix, you would see that I DID answer the OP`s question, and I have used the stuff. Compatible with wood, fibreglass, metals, glass, rubber, ceramics, hard plastics, concrete and existing sealantsIt’s very easy to use. Unlike normal glues and sealants there's no need to take anything apart. Just apply the sealant and it will travel to where it's needed.

FAO Admin - Sorry if I have stepped out of line here, but I felt I had to answer Angus. I will not respond again in this thread. Maybe I should just shut up and let, potentially, expensive mistakes be made? That is not my idea of helping people but I think we should let this subject return to the topic, Thanks I’ve been thinking about sorting my leaky windows since we were batterd with rain last month i’ll definitely be giving this one a go. Knowing first hand of the damage (potentially terminal) of leaving a leaking van in a porous state, I would regard it the height of irresponsibility not to make a fellow forum member fully aware of the threat to what may be their pride and joy.

I most humbly apologise, but the original poster did mention a fact other than the original question. That fact, in my opinion, was worth comment as I have had experience of this whole sealing issue. If he does have a leak, it certainly wont cure itI beg to differ. I had a minor leak and it did cure it. The van was still dry when sold some years later. I really didn`t want to reply again, BUT, I thought the idea of a forum was to exchange views and help each other, but perhaps like Ian Dunning I am also mistaken.
