Dug out all the panels for that side, added them one at a time clamping them together, and then removed the whole lot to drill and hold them together with cleco fixings.

It was the first time I had used it, but had seen all the bodyshops use it... went for 3M 2-pack epoxy panel adhesive, I mainly just wanted it to stop any chance of anything getting in on these seams, plus its good for some of the bits that are hard to get the spot welder too.
Its not cheap, borrowed a gun (as they cost over £100), but it still costs £60 per cartridge of stuff! You are supposed to be able to use it for just sticking on non-structural panels, but you can spot weld through it before it goes off, so went belt and braces.
The panels are a mix of Genuine VW where I could get it, and Klokkerholm where I couldn't. Its only when you start putting the two together that you see the crispness of everything on the Genuine panels, against the slightly less accurate Klokkerholm. Am not saying they are bad, they just aren't quite as good.
