I'm in the process of replacing the port and starboard bilge area vent covers (they are about 54" long) on our Sundancer. SeaRay provided me the new covers (at reduced cost) but the install is my responsibility.
I believe the failure is due to the use of an adhesive that is far to rigid and that during cold weather the cover cannot contract freely resulting in excessive tensile stress along the faying surface, and eventually cracking.
Anyway, I got one of them removed, (inch by inch), it was a real pain, the adhesive they used actually pulled some of the gelcoat off! Fortunately, all of that will be covered by the new part.
Does anyone knows what they used?
I'm thinking of going back with 3M4200 after I do a compatability test on the cover material.
Thanks in advance for your thoughts!:smt001
