Cool! I get a lot of S2 with my 8 1/2 foot Birdview. I don't know that brand but it looks good, Just do the string test to see if it's kept its shape. Maybe sand it lightly and repaint it with flat (not gloss) white.
On my first big dish, I had to run a wire edge to edge and pulled in order to bring it back into shape. Worked well after that.
Huzzah!
