I have used PVC pipe, silver tarps and bungie cords for much of the time I needed a shelter. I found my nieghbours like the idea of all that sanding
dust staying inside the shelter too. There may be some environmental issues with sanding and it NOT being contained.
I haven't lived in Canada
for many years but I do remember some folks who didn't like the idea of some the (semi) toxic stuff possibly blowing into their pot patch. They were not happy with me for other reasons too I'm sure, but thats another story.
For me I know if I open a can of paint
the likelyhood of a bug flying into it is directly proportional to the cost of the paint. The size of the bug and it's ability to flop all over the deck
is directly proportional to the difference in colour ie dark blue hull(wet paint) and cream coloured decks (dry).
Keeping bugs and errant dandilion fluff to a minimum is a shelters prime directive.....................m
