4T have you tried it without.I bet you get pin holes using it .In 25 years we have never used perforated release. Still everyone has there own ways
there sure are different ways to cook the goose.
i don't doubt that you have worked out a technique that suits your product.
but to understand a bit better how you are doing it, you might be so kind to answer a few questions. i'm always keen to learn.
when and how do you wet out your cloth?
[i wet the cloth with a squeegee on a table before laying it up on the foam or jig with measured amounts of resin for the weight of the cloth]
how much resin does get transfered into your breather cloth? is it saturated when the resin has set? do you anticipate the amount of resin that transfers into the breather and add it to the laminate?
and yes, i have tried without the perforated release film and it kinda works, but i find it hard to control the amount of resin which stays in the laminate and no i don't get pin holes from the release film because it's perforated and lets the air out into the breather cloth.
