Yes - the powder coating looks great, I was actually admiring it while on my side taking a break from being a fanny - but with less than a 100 miles on the road I would expect that to be the case!
How decent does the metal need to be -if the panels is meant to be 1.2mm and the panel on the car has thinned out - how thin can go down to, hoping to get away with 1.0 in some areas and not have to cut back a lot more metal.
With nearly the entire sill opened up I can treat the internal metal with something like kurust and then add some weld through primer. Getting the existing wax off is not going to be fun
