Could any body recommend a suitable sealant to use between two aluminium surfaces.It is an access hatch to the electronics which is housed in perspex tubing with delrin end capsand a bouancy control system using bladders. In the past I have used Sikaflex 291 but I am looking for a sealant that does not cure and less permanent than the Sikaflex. As I need to get access at the end of a trial. I am using seals for the main body of the ruv for a watertight compartment but again any ideas as most sealants can interfere with the tolerence fit of the seals. Maybe a brush on application?.
In the past I have used a Thiokol sealant for fuel tanks (aircraft) and wondered if this would be suitable?
Thanks and hope to get unstuck soon!
