<div style="BACKGROUND-COLOR: transparent; FONT-STYLE: normal; FONT-FAMILY: arial, helvetica, sans-serif; COLOR: rgb(0,0,0); FONT-SIZE: 16px; RIGHT: auto"><SPAN style="RIGHT: auto">The first forward dome in my sub was bedded in 5200 urethane by 3m (which is advertised as a marine sealant and used for acrylic ports on boats). About two years went by and I noticed that the seal looked different. So I removed the retainer and the dome literally fell out in my hands! Wasn't expecting that! Luckily I caught it before it hit the ground. The surface of the 5200 was perfectly smooth but it had lost all adhesion to the acrylic. It looked like a rubber gasket.</SPAN></div>

<div style="BACKGROUND-COLOR: transparent; FONT-STYLE: normal; FONT-FAMILY: arial, helvetica, sans-serif; COLOR: rgb(0,0,0); FONT-SIZE: 16px; RIGHT: auto"><SPAN style="RIGHT: auto">I then removed all of the 5200 and re installed the dome with 295-UV (and the black primer that goes with it).</SPAN></div>
<div style="BACKGROUND-COLOR: transparent; FONT-STYLE: normal; FONT-FAMILY: arial, helvetica, sans-serif; COLOR: rgb(0,0,0); FONT-SIZE: 16px; RIGHT: auto"><SPAN style="RIGHT: auto">The dome spent the next ten years installed with lots of dives and no problems.</SPAN></div>
<div style="BACKGROUND-COLOR: transparent; FONT-STYLE: normal; FONT-FAMILY: arial, helvetica, sans-serif; COLOR: rgb(0,0,0); FONT-SIZE: 16px; RIGHT: auto"><SPAN style="RIGHT: auto">Eventually, because of its age, I decided to make a new one to replace it (although it still looked like new). I tried to push the old dome out with a 4 x 4 and a hydraulic jack from the inside. It wouldn't even budge. I pushed it so hard that the 4 x 4 was starting to split! The dome wasn't even phased! After a couple of hours I finally took out the recipro saw and cut the dome into radiating pieces to try to pry them out one at a time. Using a crowbar, the acrylic was breaking into pieces but broken shards were still stuck the sub! It took quite a few hours to remove the sikaflex- mostly with wood chisels (heated with a torch) and a wire wheel.</SPAN></div>
