Yes, the Doculam does shrink just like the other films. But as I recall it takes a little more heat to bond to the wood. And the adhesive isn't all that thick. So some playing around with scrap wood is well worth the time to get a feel for it.

Unless you fly from a field where there are a lot of puncture risk sort of plants on the edges you don't really need the Doculam underlay on the wings and tail. 00 gas model grade silkspan is TOUGH even on it's own once doped. On the fuselage which will recieve somewhat rougher handling it's not a bad idea though. Or simply double cover with the silkspan. A coat of silkspan, two or three coats of dope then another coat of silkspan followed by a few more coats and that fuselage would be very resistant to all but the worst handling.
