I've had very good results with silicone rubber sealant. I note that West
Marine's catalog guide section specifically recommends against using
polysulfides on plastic and this confirms my experience. The sealant never
really cures at the interface with the plastic. Their catalog features a 3M
product designated 4000UV which is "highly recommended for ABS, Lexan and
other plastics". I have no experience with this material and would be
interested in hearing from anyone who has.
