I like 1/2" copper pipes in rubber-mallet-formed grooves in 6" Amerimax 
0.018" brown-painted aluminum roofing coil stock, with silicone caulk as 
glue.

Then again,  Sven Tjernagel built hundreds of EPDM bladder solar collectors. 
David Wright improved them by adding fiberglass window screen to spread out 
the water flow inside.
