I think you'll find Dave has already covered the rough edge of his column shroud with neoprene u-channel...no doubt a description already on this site! Found it:

Personally I like the Motolita spacer as it is, even with the reflections, but will probably cover the edge of the shroud if I can find a suitable bit of edging. At least my interior is black so the shroud "matches" - more of an issue with coloured interiors.
