Matt,
I `m debating on using a product called pollyspan for my wings nitrate dope then regular auto finish
Do you have any experiance with this product? it looks great!and a little more durable than Silkspan.
BTW
Do you have a before and after weight chart for the system your using verses Monocaote?
Bryan
Bryan,
On polyspan, I'm not sure.
I have some quantity of something that may be similar that has heat activated adhesive backing built in, like some fabrics. It is lighter-thinner than monokote but heavier than the paper so I've not used it on anything. I expect the finished weight after paint to be higher than monolkote. The big positive is that filling would be minimal and should be less work over all. Shrinks just like any of the polyester plastics or fabrics...with heat.
If polyspan is applied with nitrate and doesn't need much filling to seal and doesn't need heat to shrink, it may work the best of all of these materials. Would you send me a piece for a rudder or stab?
