Quoted from Tommy-dog:HSA does not charge $800 for just clear coating. If they charged you $800, it must have been for restoration and clear coating.
Here is the HSA clear coating page: http://www.hsapinball.com/HSA_PINBALL/Clear_Coating.html
The last playfield they clear coated for me, I was charged $275, but that was about 3 years ago.
Says $385 for clearcoating on that page.
