No, I don’t see why it would, it would just waste resin. The only reason release film effects anything is because it creates a bigger difference in the flow front. Your flow front isn’t even, what you are witnessing happening on top of the laminate is delayed on the surface of the laminate, so the flow front on the surface of the laminate will be lagging slightly behind the flow front that you can see from the top. Release film makes this difference even bigger as it takes more time for the resin to penetrate down through the laminate stack, and so if you let it flow too fast then you may trap voids between the two flow fronts.

Throttling the resin flow is what will fix those issues, as it slows the top down and gives the resin more time to flow on the surface.

That makes a lot of sense. Thanks for explaining.

I did another layup last night. I eneded up doing
Mold
Teflon surface sheet
3 plies 100gsm textreme spread tow
Perforated release film
High porosity teflon coated fiberglass
Red flow media
Bag

We will see how it comes out tomorrow. Ill post pictures also.

Sorry about not posting pictures. Got swamped and then was at the Rolex 24 all weekend. Had to go see the GT! This layup came out very poor. The printing from the red flow media was much worse than the white or the green. I went and did a layup of all of them on one piece of flat carbon on the foam mold to pick which one is the best. Will be pulling it tomorrow evening.

The screen works really well for not printing. I dont know if it is too slow or not though. Here is a link to a video. The distance between the two connectors is 3-4inches. It must go a distance of 18 inches and on some of the bigger wings 40 inches. The set time of the epoxy is 45 minutes at 80 degrees farenheit.
