no it is not
it is not a bad covering tho - of the little I have used, it goes on pretty easy - but have not checked how fuel proof it is yet

Kim,
The Brodak web site shows pix of a "heat shrink covering" material that could be similiar to polyspan. The picture shows very little detail......

Jim,
Yes, this is page in the catalog I saw. Wynn provided some info. I'm curious what those who use it have found. I would like to know if it is a polyester tissue, how heavy, etc etc.
Thanks,
Kim

I have used the Brodak heat shrink covering on three models over the last 2 years. I really like it. It holds dope and seals very well. I use it only on the wing with open bays. I would not use it over a sheeted fuse. The best thing about it is that it is easy to remve wing warps with it. Just use a monocote heat gun, twist the wing to a true position, then gently heat the covering and presto; the warp is gone. I have used it on a Ringmaster, an OT named 'El Diablo' and a Veco Thunderbird. It may be slightly heavier than silkspan, but not by much.

Do you have to seal the seams or are a fuelproof without it?

After I attach the Brodak heat-shrink covering, I cover it exactly as I would silkspan. It looks like silkspan and it takes dope just like silkspan. About 3 coats of clear, followed by color of your choice.
