Windscreen adhesive

I need to re fit the glass in to the front screen of a series 2a what have you used in the past to stick it in ? I bought some thing from Amazon called window-weld ribbon sealer but stupidly did not look where it was being sent from ;-( America and its still not arrived a month later. I can't find it on eBay or amazon in the U.K any suggestions as to an alternative ?

sikoflex is the windscreen stuff most companies use...wear gloves!!
