How to shrink the back glass of a Kia Soul.
Option A.) Dry shrink it. If you’re using an H-pattern, this might cause issues. An easier method is to simply tack it straight across. Also, let the edges float and put some air under the corners with the heat gun if you’re having issues with the corners.
Option B.) Do a wet line directly in the middle, going horizontally. From there, do a shrink lasting about 3 minutes max.
