Release fabrics what do you use?

[Commander-147]

Some people tell me they use mylar for applications where you do not want epoxy or polyester resin to bond such as a backer plate for a hull repair or fabricating frp panels. Others have told me they use visqueen. What is the best thing to use and where do I buy it and how much does it cost?

I use kitchen cellophane wrap...... or packing cellophane wrap (a little heavier).

Plastic drop cloth works pretty well too.

I use two things depending on the job:

1) PVA. Brush on two or three coats and let dry, and you magically have a plastic film covering the part/plate/whatever. Dried PVA films are just like green Saran-Wrap except that they dissolve in water!

2) 100% polyester taffeta from the craft or fabric store. Swoop into the fabric store with macho swagger. They'll have tightly woven polyester (taffeta). Out here in California it's usually $6 a yard in the 54" width. Pink seems to work best. The polyester taffeta is very similar to Peel-Ply, a commercial product intended for the same use (see http://www.aircraftspruce.com/catalog/c ... eelply.php ). Dacron is polyester.
