loads of fun...
you can roll it over something like an oxy bottle gently in both planes should be enough for what you need, you gonna spot an edge strip round it and spot this to the rear of the aperature or have you another cunning plan

That was what I thought, something gentle to put a slight curve into it. Yes I'm going to give it a flange...ehem....and spot it from the frot and the back, them seam it inch by inch; opposite side at a time.
Just for to get the van now!! It's like looking for a needle in a haystack!
Why seam it? panal cut 1mm undersize, 1"piece added all round 1/2" to infill 1/2! left then spot this as well, you would then have it filled with as good as no distortion and of course the lip would give reinforcement to the whole lot.
what you do with the minute gapo is up to you , if it was me I would lead it real quick and easy job done, remember you dont need structural strength you could fill the gap and it wouldnt be a bodge

Ahh. ok ..not the best easiest place to learn then,
use a good metalic based filler for the skim,,as it will have new metal behind it will not flex, there is no worry from water from the inside as you will be sealing this as well so its only cosmetic.
