Rear wheel arch removal

Hi guys,
My rear arches have become holey and i was advised its easier to replace than try and patch them
It the bit thats visible when you open the back door not the entire arch
I got my replacement panels from Paddocks.
Looking at the car and the panels it seems a load of spot welds and a couple of mig "tacks" is all thats holding them on?
Is there anything to watch out for doing the simple (looking) job?
Cheers Dave

I posted on here how I did mine, its quite an easy job.
As you say just a few spots welds and short mig welds.
