Existing roof skin removal from a 69 RR pillar coupe.

What "tricks" are there when one wants to remove the roof skin? I have all of the spot welds cut out and now need to get some help \ ideas on how to overcome the "glue" which holds the roof skin to the ribs.
Thanks.

On the sealer spots'you can use a hand held torch.Propane is fine.Put some UP pressure with a small pry bar or screw driver and it will release.

Get a couple seam buster blades and work your way round the roof.
