Beautiful set in a gorgeous electric blue!  Works better than I could have hoped for on my small patio. I am so pleased that it came fully assembled. 
I had read the reviews about potential water spots, and so I did a light coat of clear rustoleum on the upper table top and seating surfaces. A little extra protection on the heavy use areas sounded like a good idea anyhow. 
I left the lower areas (legs/table base, etc) untouched though.  The set did get rained on over night last night, and thankfully I have not seen any water spots as of yet on the sprayed or non sprayed areas. So that is very promising. The rain water just pooled on the surface, and wiped away cleanly.  All in all I am very glad I purchased this set.
