Fiberglass cloth lifting off plywood when removing mylar sheet

Vacuum is for flat surface too. If you had used it you would not have had the "lifting" problem you are posting about. Just that simple. Again, follow @JohnCoker's videos and you'll be golden.

Unfortunately I don't have a vacuum device, and have to make do with the supplies I have or can easily obtain. But I do try to follow John's (and others') videos as much as I can.

You can buy an old Food saver on ebay for just a few buck, last one I purchased $30. The bags are the most expensive part, but since you can reuse them, the expense is negligible. I'm not trying to be argumentative, just want to be sure those following this thread understand that it is easy to do it right.
