Great concept Scott, using Corflute is a bit of genius!
So far I've been throwing a large plastic table cloth over my gear table, but I have no where protected to keep books open, write notes, etc, and worse still it ends up with puddles of dew all over it.
Having seen your simple but very efffective solution I think I need to build one like that straight away!
I haven't measure my table yet, but I'm almost positive I'll need Corflute panels about the same size as those real estate signs that get hamered into my footpath every weekend...
