How do I adjust the tension at which the hardtop closes ? I.E  How do I adjust the closing latch to make a tighter seal when I lock the top down ? 
  Also is it possible to adjust this latch for the convertable soft top closure to be a tighter fit too ?  Or should I 
not make this seal overtight ? I have had a water intrusion problem, which I have solved, but now find myself obsessed with preventing any water ever getting into my car ever again !
