Tony;

just had customer with similar problem. What mark wrote is correct. Fine air
bubbles will cause not only pacman bites - but very fine pitts - maybe
hundred to thousand in very small area. Check out tank - u will notice color
of tank is also not like others - more effervecent shade to it - like gray
blue - gingerale sparkle to it. Don't have  ur original file in front of me -
if pitting is larger than minute - can be another cause to.

if need more help - e-mail me back

regards
