Trying to Thicken a Lofted shape made into a Surface

Hi, I'm trying to design a cover for a wingtip navigation light for an R/C glider. I drew the geometry for the end shape of the cover on the Top Plane and Lofted it to a Point on a Plane about 51mm above the Top Plane and set the Start profile condition to Normal to profile with a Start magnitude of 2.8. The result came out good. Then I deleted the two flat surfaces to end up with an open object, which is what I want. I just need to Thicken that object by 1mm from the outside in, but that is where I'm at a dead end. I would appreciate anyone's input. Here is a link to the public document. Thanks very much! Tom.

If you look at the curvature of the surface you created (there are various diagnostic tools) you'll see "a lot going on" which means it will be extremely unlikely to thicken this surface. Wingtips are notoriously difficult things to model cleanly - the patch structure specifically. So it will probably be necessary to rethink your approach.
Okay, thanks, Greg. A friend of mine came up with a possible solution using the Slicer, but I will have to print a prototype to test fit it.
