Just dropped the GT's headlining to fix a perennial leak from the sunroof. Having got rather wet coming home from the Huntingdon rally
I'm doing the obvious stuff like clearing tubes and checking for rust holes, and even cleaning up the sunroof mechanism
I want to replace the mastic that was already there and put plenty more of the stuff around - I was talking to a very nice guy - Jabba? - at Huntingdon about doing this. But B&Q and Wickes stock hundreds of varieties of tubes and for some reason none appear to be labelled "non-setting mastic for use in Citroen BXs to stop drivers getting wet".
So what exactly is the best stuff to get?
