Vinyl Top in Cold Garage?

I bought a vinyl top from Legendary for my '70 E-Body several years back. Turns out the seams that run from front to rear were cut unevenly. The top is made of three pieces of vinyl sewn together with two seams running from front to rear. The seam itself was sewn straight as an arrow, but the extra material that makes up the edge ends that are folded over for about an inch were not. They lay under the top to make the raised seam next to the stitching that's sewn from front to rear. Well,they were cut uneven for some reason.

I took pictures and Legendary warrantied the top with no issue, but the second top was about 1/2 as bad on that seam's trim job too. Bottom line, make sure your extra material along the seams is trimmed perfectly straight, so that once the top is glued down the seam looks straight along the raised portion of extra material. Does that make sense?

If you heat your garage and put an electric heater inside the car while you work, you can probably pull it off safely. Heat rises, which will help heat the roof of the car, but large drafty garages are hard to keep heat in.
