4 Ounce Breather and Bleeder Cloth - 60 Inches Wide - Polyester Cloth - Binder-Free - Conforms Closely to Contours of Part

Standard cotton batting that allows air to escape during vacuum bagging and forming of epoxy fiberglass, or carbon fiber parts. Good value for the money.

I’ve been using fibre glast products for decades. They are consistently good and drama free. This breather cloth is the stuff you pack in the bag (along with the resin and fiber glass / carbon fiber) so that you can pump down the whole thing and get the air and bubbles out. There are lots of videos out there showing how to use it – and it does work. It’s all the better getting a great deal on it. Made my day.On unpacking... yup. Fibre glast breather cloth. Exactly as expected and desired.

Great product which helps resin to flow in the composite infusion process. The breather cloth is made out of quality material which helps collect excess resin. This cloth also contributes to a professional surface finish.
