Ultracote around concave curves

Does anybody have any good ideas for getting Ultracote around the inside of a concave surface? The top wing of the SIG Smith Miniplane, a .40-size conversion, has a notch and I have no experience covering such a shape.

Some good shots of the top wing are at http://paulsplanes.fws1.com/smithminiplane.htm

My technique uses a soft leather glove (chamois style or one of the Monokote Mitts) and a heat gun. It is hard to describe but you need to shrink the covering slightly before pressing it in place. Attach one end to a smooth/flat surface and work towards the concave curve. Working side to side heat and press the covering in place with the gloved hand. When you get to the curve you need to heat sufficiently to see the covering shink/pucker then press while still warm. Keep working side to side along the concave surface. Practice on some scrap first and it really helps if the surface is anchored/clamped in order to use both hand freely. Hope this helps........
