: Ulrik,

: I don't know why u want to use Dacron but in case this is not
: mandatory, I would suggest you to contact www.cfweber.de and
: ask about crude cordura, before heat treatment, while, as Bill
: suggested, you need to shrink this on the frame. Actually you
: could contact any textile manufacturer(not reseller) in this
: respect, search in this directory www.cordura.com to find
: cordura manufacturers still active closer to you, Cordura is a
: texturised nylon 6.6 that offers an very good grip for the
: sealer while looking a bit fluffy compared to ballistic. You
: also can find ballistic usually, at the same manufacturer.
: Hope this helps.
: If not positive, contact me, I usually buy larger quantities and
: they take me seriously :) but the direct shipment to you should
: be the best solution.

If he's trying to do the fiberglass over fabric method Dacron works better than nylon. Dacron has a very similiar stretch compared to fiberglass, nylon even Cordura has considerably more.
