I JUST GOT A FREE PLEXIGLASS TANK FROM MY BRO N LAW. IT IS 6 FT LONG AND HAS SHARP CORNERS NOT CURVED. THE FRONT PLEXI PANE IS SCRATCHED SO DEEP I AM AFRAID ITS BEYOND A POLISH JOB. DOES ANYONE KNOW IF I CAN REPLACE THE ONE PANE? AND IF SO, HOW DO I GO ABOUT SEPERATING THE "WELDED" SEAL? I DO HAVE THE CHEMICAL COMPOUND TO SEAL PLEXI TOGETHER, BUT I NEVER TRIED TO SEPERATE THE STUFF. ANY INFO WILL HELP!!!!! THANKS
