Got a roll of masking tape and, on by one, taped up the headlight rims, the bottom of the windscreen, the two verticals each side, the side screen tommy bar holes, the screw recesses for the mirror, the gap between the running board and the rear wing, and even the door with me in it, all to no avail!
Anyway, it was a good excuse to go out int it :-)
I'm now wondering whether its the leading edge of the bonnet (I already did the trailing edge), or, possibly the gap between the headlight glass and the rim, rather than where the seal is, which I already taped. Good excuse for another run out ....
