Just got this in from a reader:
Hello Paul, I have a 29 foot Tylercraft sailboat. There is a hatch in the forward cabin with a plexiglass top which is now discolored to a yellow orange color. Can anything be done to bring this back to a more clear look? Thanks,
I've had good luck in buffing out discolored Plexiglas with Flitz Metal Polish. I used the paste type polish and an electric buffer. Be careful not to overheat and "burn" the Plexiglass. You can fins it at most marine stores like West.
