just another quick question.....
i see everyone who does vacuum bagging with wings using a plastic product called Mylar.
can i use baking paper as an equivelent as it is non stick, or is it too soft and will potentially crease in the vacuum bag.

Hi jase, wax paper is way too soft. I buy my mylar from the art shop and its about 80-100 micron even stiffer would be better. That way you don't get the rippling effect. A nice smooth, shiny finish is what ur after. And also wax ur mylars before use.

Guys as far as I know, acetate is very different to Mylar. Acetate is the stuff that you can heat and mold to make canopies etc - warm it up and you can bend and stretch and shape it, and when it cools it sets in the new shape. You can get sheets of it from hobby shops. Mylar doesn't stretch like acetate. Maybe I'm wrong?? It would be good to get some comments on this if someone knows.
If you're looking for an alternative to Mylar, get some thick-ish laminating film. The shiny side of lam film is as good as Mylar - nothing sticks to it, and I suspect Mylar is the same material but much thicker and without the glue layer that's on one side of lam film. I use it a lot for small jobs like repairs or glassing balsa fins. The epoxy looks like a mirror when you peel the lam film off.

Hi Guys, I'm new to the forum. Haven't used mylar recently but have in the past used it for glassing up rudders and centreboards for boats. Back then we were sourcing mylar from the local sailmaker. Mylar is commonly used for see through windows in sails so it might be worth trying a sailmaker. Cheers

Found some more info on this Mylar supplier...
There apparently called OBA (o'brian - aim).
Address is - unit 2/19 Murdoch circuit, Acacia Ridge.
phone number 32761414.
About the Mylar -
thickness is 0.35mm - 350 micron.
The sheets are 915mm wide and available at many lengths but sold in weight and not length.
Its $15/kg and you get approximately just over 2m per kg so its fairly cheap.
Im hoping to get some soon and try it out.
Hope it helps...
Abdullah.
