The smoked plexiglass sliding hatch on my boat seems to be warped and I am not 
sure why.  For several years, I have had a thin flexible 50W solar panel 
velcro’d to the top of it.  The spacing between the panel and the bridge that 
supports the traveller was initially tight, so I ground the fiberglass with a 
Dremel so the panel would fit underneath as it slid.  But I noticed that 
however much I ground it, the spacing would decrease over time, so that last 
summer, I had to lean on the panel to get it to fit underneath.  Once out of 
the sun, it would relax some, but the situation got worse as the summer wore 
on.  I pulled the whole sliding panel and brought it home and the plexiglass is 
clearly warped.  I can’t see how the solar panel on top would cause that to 
happen because most of the time, most of the plexiglass is out of the sun, 
covered by the solar panel.  I guess I am going to have to replace the entire 
panel as it is now seriously warped in some areas.  If anyone has any thoughts 
on what caused this and what to do about it, I would appreciate the advice.  
Thanks- Dave
