72 cutlass s roof skin replacement
Have a 72 cutlass that had vinyl. The roof was in pretty bad shape and I replaced some metal and but bondo over it but the bondo keeps cracking. I think it’s too thick and the roof is too flimsy from all the rust.
Has anyone replaced the roof skin? I know it’s spot welded on the front and back windshield areas. Is it welded along the drip rails as well?

Thanks. What type of spot welder tip? I've just read some people use panel bond for the sides along the drip rail, is that better or worse than welding? Does anyone have photos of doing this? I couldn't find any that mentioned the drip rail

The drip rail spot welder tips look like this.
Panel bonding has come a long way in the last 10-15 years. The real problem is cleanliness of the bondline. Any grease or oil (including oil from your fingers) can compromise bondline thickness. Of course you need enough clamps to go all the way around. I'd go with spot welding myself, but I have all the equipment.
