I'm currently in for repair and paint after hail damage. Many planes on my field were hit by a storm. After deductible, the insurance company is picking up 100% of the mechanical repairs and about 1/2 the paint job. Their reasoning to me was it's didn't hail on the bottom of the plane.
You must be very careful what you decide you want in working with an adjuster. If the costs are over 50% of the pre hail insured hull value, they will just total the plane, pay you off and take it away. If you are okay with that, then fine, but otherwise it might be a bad decision to have them cover too much.
While they agree to pay the repairs and a negotiated value of the paint required, there is another step - they will probably offer a lesser amount in cash to just walk away without fixing anything. Quite a few owners on my field chose that and just fly with dents.
The repairs include filler after the paint is stripped on the fuselage and wings. It's not bondo as people think, it's flexible and light - and not much is left on the plane after they sand it out. Lot's of opinions about this step, but much of the negative it about products decades ago or applied poorly. The larger cost and work is for ailerons, stabilator, flaps - essentially all the moving parts except the prop need to be taken off the plane and reskinned or replaced.
Of course once you start this work, the temptation to add things is pretty strong. In my case that's modern wing-tips, slight upgrade in paint designs, led lighting, removing strobes, body repair unrelated to hail...
Figure a decent paint job is $10-$18,000 - insurance pays half.
Mechanical repairs are harder to estimate without them looking at it - in my case about $18,000.
What you decide to add yourself - bottomless pit.
