The seams on both roll bar covers seem to be opening up, is this normal or is there a fix? Looks like they just snap together? Thanks for any help.

 

Does it spend a lot of time in the open sun withthe top down. Only thing I can figure is that the covers may have warped a bit in the sun or the molds that create the snap together coupler thingys have weakend over time. Have the covers been apart alot for mods and what not?
