Well...........I do really like Alu and my wife really likes it, I never should of shown her a picture of the ATMA tear!
I may reconsider tho as it will cost an esay £500.00 I reckon, and thats before the trim and edging etc! She wasn't a fan of the canvas when I did some test panels tho, what other options are there? Fibreglass looks like a lot of work and the epoxy version isn't cheap!
If only I could get a good finish with hardboard or OSB (although OSB is too thick)................. Nice and cheap!
