Thanks Glen. You're right of course, and I'll get around to it eventually.
I do have various cans of sealant, but it may take a minor wetting to prompt me into action.
I did consider marine ply when getting the supplies but for my modest use I really couldn't justify the extra cost. I mostly set up for about an hour's viewing, reasonably early in the evening and the location doesn't seem especially prone to dew, although I can recall a longer occasion when the table I had set up was half in the shed and half out and it was dry one end but starting to get wet at the other.
But these are lame excuses.... and a coat of something would look good too. I'll add it to the list...
