when you take the tops off and then put them back on couple of things to keep in mind:
check the weather stripping - I noticed after some time off in the heat, the stripping on mine shifted slightly, guess it didn't get glued all the way. I just make sure it's all in place and sitting where it should be.
Also, if you out the interior long bolt back on, don't make it too tight. too tight makes the front of the panel lift up a bit. I leave mine off, no issues in 3 years
