Managed to get the 1/4 on and some what welded on. The spot welding was hit and miss. I decided against the copper weld through as after lots of research, it appeared to be a great choice to weld / spot weld through but it offers little to no protection in the seem and most of the areas I'm spot welding will see lots of water so I stripped it all back and replaced it with Bilt Hamber Electrox which has the highest Zinc content I could find. This will sacrifice its self first rather than the other way around with the copper weld through.
Now, the only issue with that is that its not exactly a weld through primer, although lots use it that way, so I had to mark the areas with 13mm stickers on both the body and the 1/4 for the spot weld points.
The TIG spot welding was very inconsistent with some spots coming out great and others just not wanting to no matter what I tried. The common issue I came across was the top layer burning a hole before the heat had a chance to hit the second layer. The only upside to this failure was that it left the perfect size hole to MIG plug weld through. So I reckon I have about 1/2 spot welds and 1/2 plug. Either way, its on and on well. The other failure was just an almost immediate burn through of both layers!
I am really happy with the way the 1/4 went on fitment wise, boot, door, arch all great and is actually better than the factory fit and finish. This took flipping ages. Must have taken it off and on about 50 times while continually tweaking things
The gaps and lines are spot on so really happy about that 
The last pic is what an absolute mess I'm working in currently LOL. Car also looks like its just been pulled out the Fukushima fall out zone, ha ha!
Good progress all in all. More to come over the next few weeks.
Bad!
Decent...
