how do i fix a zip on a coat that splits when you try to zip up?
I have a 2-way zip on a coat with two zippers. When I try to zip it up with one zipper and the other is left at the bottom, the zip (teeth) does not stay together and splits inbetween the top and bottom zippers. It is quite a new coat but not as new to return it and I really would like to fix the problem. Im thinking maybe the teeth on the zip are to rough or need oiling? Not sure, would appreciate comments, Thanks.
