My experiences
I just got back from a Long Island to Jacksonville, Florida delivery, so I'm stepping in here a bit late. But...I've done most of this already, so I've learned a few things the hard way. Here are some:I tried replacing parts of the Gray ports and quickly gave up on that. I ordered new ones, thinking my old ones only fell apart from age. The new ones must have gotten old very quickly.I installed the Newfound Metals ports about 4 years or so ago. They are a step above the plastic, no doubt. However, here are some drawbacks I've learned.The adjustments for both the locks that you do manually to close them, and the adjustments at the top to adjust at the hinge will not stay set. There is no provision to keep the screws from moving and I find I am constantly having to adjust them to keep water from coming in. I've tried to jam some material in the thread to make them somewhat like a lockwasher, but have had limited success.They must be screwed down very tight to hold water out. The rubber seal around the window is not water tight, just a loose fit, and depends on being closed tight to make a water tight fit. Water will seep between the glass and water otherwise.At least on mine, the bronze tarnished badly and quickly. This won't bother some people, but it wasn't what I was looking for. Newfound Metals sold a coating of some sort that was suppose to prevent this but it was a do-it-yourself deal and I didn't want to mess with it. It might be a way around the tarnishing if they still sell it.Reparing and sealing the coring around the frames was mentioned. That is good advice, and I had to do most of mine. It's not fun, but can be done. However, I don't think much of my rotting came from leaking around the ports, rather from the dorade boxes. they are prone to leaking from a design/fabrication defect. I've written up some info on this on my website which may be of interest. For some reason, I can't get the website up right now to paste in the exact address, but if you go to:http://www.geocities.com/rainbow_chaser.geothen follow the link to the upgrades page, look for the dorade link you can get there. If I manage to get it up later I'll add another post with the link.Good luck, it's a fun job! :^)Gene Gruender
