i went in intending to get 4mm marine ply at 40 bucks a sheet , but i had a look at it and they had 2 dark sheets and 2 light coloured sheets and both were very plain looking bland no grain feature at all , and only 2 of each meant i could not get a spare or grab another matching one next week should i have a disaster ( swamp girl 12 , 2 sheet build ) .
so instead i came out with 3 sheets of 4mm exterior hardwood ply with a bit of nice grain @ $24 per sheet plus i grabbed a sheet of the same stuff in 6mm for frames and stuff like that .
yeah hardwood is a bit heavier but i figured this is only a 12 foot swamp girl and we wont be carrying the thing very far so the little bit extra weight should not matter .
best buy of the day after a bit of chasing around was a very nice drywall square wish i knew about these years ago i could of wore 2 of them out by now if i had ,very cheap too ,looking at it i thought here we go this has got to be worth 80 or 90 bucks but was only 24.90
