Re: rebedding my hatch lexan (if that's what it is)
Brian Atkins, Atkins & Hoyle Ltd. There are a lot of different possibilities when choosing the right lens and adhesive for repairing your hatches. We find that a cast acrylic works best (Lexan is stronger, but clouds or crazes much faster). Some people prefer a simple Butyl Tape to seal this in, some prefer the stronger 5200. We find that something in the middle may work best.
Butyl Tape is easy to apply, but as the primary sealant it does not seam to hold the seal quite as long as some of the other glues.
3M 5200 works great as a sealant, and for strength. But we find almost all boat owners need to remove their hatches or ports at some point during their adventures - and 5200 is simply too strong for this application (many have broken their hatch simply trying to pry it off the boat).
Most hatches and ports will be secured in place using either a self-tapping screw, or by being through-bolted - not by glue (other through-hulls may vary). The adhesive you choose should only be used to make the opening waterproof. Often some type of silicone is more then sufficient for the job, just make sure to clean both surfaces prior to gluing.
Feel free to take a look at our website (atkinshoyle.com), where we discuss how to go about resealing your hatches. If you have any questions, feel free to give us a call (613 354 1919).
