Beckson Port Comments
Don't know anything about the Grey ports but with Beckson the ports can be ordered with the thickness (the portion that sticks through the coach roof) in 1/2-inch increments or to a custom dimension. They are also available in black or white. Perhaps the Grey ports could be had similarly? No harm asking.Would highly recommend replacing the ports with something that is a "drop in" and doesn't require any custom cuting and fiting of the coach roof. This is a messy, dirty, time consuming job. Also the resale value would probably be better keeping the boat looking original.With regard to a UV plastic protection product I would recommend talking to a technical person at 303 Products, the same people that make the 303 High Tech Fabric Guard and 303 Aerospace Protectant for use on Sunbrella (http://www.303products.com/). They have products specifically formulated for UV protection on certain types of plastics. They could probably also advise if the UV coating should go on before the sealant or after.Speaking of sealants: For some items, such as DOW sealants, the black version has better UV inhibitors than the white version of their product. While this may not be true across the board it's something worth considering when making color selections and when talking to salespeople. With regard to how well a product holds up under UV, the plexiglass in the window of the port will need changing after a few years due to crazing. Some people are more sensitive to how the "glass" looks than others. We went about 10 years and couldn't believe the difference in how the new glass looked. Having known that I would have changed them sooner. The gaskets, likewise, will need to be changed before the port frame.
