So long story short
I had an FRS trunk, we took off the wing and filled the holes by making plates and running a circle of weld around until they filled up
i took it home and hit it with a layer of primer till i could get it painted. at that time we mounted the new wing. and got it straight,
when the paint guy was ready i took the whole trunk off and brought it to him and thats the trunk with the wing mounted and painted.
no blending. and he did a swell job
