Wrinkles when vacuum-bagging :(

I noticed that I have got a couple of "bumps" that I wonder how I can remove and to prevent for happening next time. Can I just sand it off (I will add several layers on top of it)? I wrapped the CF in two layers and was very careful that I didn't had any wrinkles. I used peel-ply and breather. My concern is how can I assure not to have wrinkles when I'm vacuum-bagging? I mean when the vacuum is applied I don't have super-control if the CF wrinkles (since I can't see it through the breather). Should I only wrap one layer at a time? (I intend to wrap 6-10 layers depending on which part I'm making. Note, that I don't use a mold, but a plug and you can see the wrinkles in the attachment / Marcus Attachments bild 2.JPG (683 views, 1.00 MB)
