Bubbletop cracking problem??

So I started the roof on my 61 and noticed their is a hairline crack on the roof deep under the paint, it has to be no more than .010 thousandths wide but like an inch long, and on the other side near the same exact sopt on the other side, it looks like it is cracking as well, is this going to be problem??? I was thinking just hit it with the spot welder and grind it down and smooth it out, does this sound right or will I end up making the cracks worse. oh and is this a common problem?

nah the car was NEVER of frame, im working on getting her there, the kid who had it 15 years ago was doing doughnuts in a lot and smacked a pole, it all came out pretty nice, I went over the car with a fine tooth comb, the frame is'nt tweaked, nothing. Its not where the quarters meet either its on the roof, by the corners of the glass maybe 1 inch in on the body, from the glass would be, its like its wants follow the pillar going down, fill her up with some lead or what? OR is this going to be a big problem down the line? I deff need to get pics of these up on my blog, theyre not horrible, its prolly because i like everything perfect im just picking everything apart HAHA skim would know what im talking about

Are these lines where the front windshield post meets the roof? Or on the back side on the top of the post where it meets the roof?
My bubble top has these lines where the roof meets the front posts.
Seams it is a line in the factory lead job.
I used filler on mine. Dont think you could weld it as it is in the lead.
I may be wrong...but ..... I doubt the roof will come off while driving it. LOL

A buddy of mine had a 64' with the same problem and we asked the old timers and they said it was due to X frame design. The body twist's a little eveytime a turn or accelerate happens, over time the roofline weakens. It's like bending a pop top back and forth until it breaks off. It just the nature of the frames and that's why GM went to a full frame in 65. Hope this helps.
