If anyone recalls, I put the black PL on the hull sides, bottom, seams at the bow. And some on the bottom from bow back 10 feet I mixed 50-50 with 1/32 milled fibers.
Well it is just fine, no leaking, so swelling, no nothing. Been out on some high power runs and it has survived. But mostly we only go about 6 knots close to home port. The fishing on the Poquoson flats we have not had much success, so we are planning to go over to the CBBT and also the cement ships again where the fishing is better. It seems like 20 yeas ago, there were more fish close to home port, but it seems to have gotten like a desert this year. Last weekend, we were out with about 10 others boats, and no one caught a thing. We stayed on late into the evening and then caught some small croaker and weakfish.

I am glad to hear the PL has worked for you. Sorry to hear about the fishing, lets hope that isnt the permanent state of the fishery.

Unconventional,... Yes, but that doesn't mean it can't be successful. Glad to hear it is going well. Those 37 ft Eggs are very attractive boats, unfortunately they had pretty lightly built bottoms, glad that found a recipe that works for you.

Good to see you posting again. I like seeing the old Eggs and Pacemakers show up on occasion. In a former lifetime, I had a 32' Pacemaker, so I am familiar with some of the problems you experience from time to time. I took a more "conventional" approach to the boat's maintenance, but it never seemed to keep up with the deterioration, and that boat was only ten or twelve years old when I bought it. Some of the things you do causes raised eyebrows at my end, but the fact that yours is still floating and looking good speaks volumes; most of them have been gone for years. I hope you stick around and let us know what's working and what's not.

Nowadays I stick to little boats that can be kept in the shed year-round. That takes the urgency out of the maintenance schedule and makes it fun again.

Thanks Thorn, I was clueless what PL was.

Hi, just updating again. The Black PL is perfection. Anywhere it was placed underwater has remained fine, no leaks. And the hull sides I undercoated with Black PL look super, very smooth, no possibility of seam cracking. Paint still shines and looks just like the day it was painted.
Black PL has also stayed stuck onto on the hull bottom and the old antifoul paint I resuscitated by mixing in methylene chloride and some linseed oil still is working.
All the boat seams where I used DAP Dynaflex 230 also look perfect, no cracking.
The bow seams I ripped out and filled with Black PL also perfect, no cracks, no rain gets into the hull.

Where the deck toe rail ends, water does pour down the side of the hull and the paint is greyer from dirt.
So total success. We made some white water rough trips across the bay. All has been fine.
I need to rebuild my starboard IHC engine, it smokes under a load. I may have ring or piston issue going on.
I plan to do that this winter, time permitting.

If anyone wants to see those pictures, here they are
I had closed the thread as it was getting too hot headed with negativity for my liking.
AND all the glued in plank repairs are still PERFECT, no loosening, leaking, rotting, so far nothing bad happened like some were forecasting.
You can not even see any repair was made.

I don't know about that. They might not be interested in endorsing an underwater use.
I am pleased with it so far. 6 years or so ago when I first had put on the Permaflex, I also trialed some Black PL underwater on the hull on top of Permaflex and it had survived, so I knew it would work out.
I really liked the results mixing with 1/32 milled fiberglass fibers (about 30 to 40% fibers). I would be coating the whole boat with it if needed. It stiffens-strengthens- toughens Black PL mixing it with FG and it still has give, meaning it yields. So it becomes a little harder coating and a little easier to sand and easily smooths flat using a rotary wire brush. I did that on the bow area back 10 feet underwater, thought it might help if I whacked into something.|;)

PL Marine Sealant (use above and below the waterline) - $12.97. Versus $5.85 for the S30 flashing sealant.

Still doing great, no peeling off, bubbling, nothing. The Loctite PL S30 is solid on the hull everywhere.
And no leaking either, no hull cracking, wracking, splitting, twisting, warping or rotting.

Not a single hull repair I did on the hull planking has leaked or moved, no traces of a repair can be seen. I had coated the aft hull with a layer of Black PL, if you recall. It is still smooth and nice looking under the paint.
I used Dynaflex 230 in all my above water plank seams and they are perfect. All the rot plank repairs are also great. I had cut out sections, treated the wood with Alcohol mixed with boric acid and glued in new small section of mahogany. Dynaflex 230 turns into a hard rubber when cured.

Glad to hear that the Loctite black is holding up. I tried using Loctite (white) PL 375 construct adhesive for my boat carpet. As long as it was dry, it worked great. The first time it got submerged, it fell apart. Read all about the floating carpet at http://boatbw.blogspot.com/2016/08/pl-failure.html

I'm pretty sure this has very similar properties to a product called Tiger Seal here in the UK, it's awesome stuff & it appears ideal for boat duties. Essential a PU sealant rubber compound.

It does look to be very similar.

Great. Glad to know it's working out well. I've used and tested PL Premium and have found it to be quite good. I read your old thread. Wow, such angry responses. Thanks for the update on your "unconventional" repair.

You really nailed that right!
I do hope some people get over such righteous indignation.:d

Still working fine for me.

I moved boat to a new marina in Seaford Va.
This new marina has an angled slip. There is this bolt that sticks out on the finger pier, so guess what happened.
We had a couple storms with high winds.
The bolt rubbed hard on my hull side. And did not penetrate the black PL coating, but did rip off some of the white paint.
I will take some photos and post. But I was very impressed how the black PL did not get damaged.

Without the underlying black PL rubber, my guess is the wood would have been gouged and scraped badly.
I have fenders out to protect it now.

Hi Sdowney. Good to hear from you.



This new marina has an angled slip. There is this bolt that sticks out on the finger pier, so guess what happened.

What I do, is I get a crab/ lobster trap float and cut it in half. Then impale it over protruding bolts at docks and bulkheads. I usually have a couple of these floats aboard, as I pick up the ones I see adrift. Of course, other types of rugged foam would work as well.

A good idea. It is typical finger pier. That bolt supports the 2 x whatever beams and passes into the piling.
When I first put boat there, I did not think would be a problem. I now have 3 large fenders.

An angled slip does odd things with lines as the boat moves forward back, it allows the boat to slide sideways more that what your used to with a slip 90* to the dock.
here are some pics of the new slip


shows the offending bolt, on the right side.

Got my Bimini Top up, I had to repair it after a bad storm tore out the stitching. Threads don't last.
I hot dogged the 1 " SS frame longer so that it is now 7.5 feet to the deck. I glued the ss together with the PL Premium.

Truth is, I do have a sewing machine, but when repairing the top, I decided to glue the Sunbrella fabric together with PL Premium.
And for the top, I lashed it onto the frame with blue polyester cording.

To reinforce the top's lashed edge, I glued in a 1/4 inch vinyl covered galvanized steel cable. Glued cable to fabric with, you guessed it, the PL Premium. Then drilled holes for the lashing. No grommets are needed. The glue and the cable hold it, has not shown any signs of unraveling around the holes.
It has been up for months, and has held together fine. Great glue.
Picture album showing big patches glued on with PL Premium glue. I used a notched spreader, then weighted down the fabric.

I had made the top many years earlier by sewing, but was somewhat inexperienced, so it was not perfect. I decided rather than start over, to simply patch the sunbrella and as an experiment try the glue. Happy to say it is great so far. Has held up in some high winds.
Picture of how it looks lashed with the cable providing lots of support for the lashing.

Picture where paint was rubbed off by that bolt.
Otherwise the hull side paint has held up well since 2014.
This summer plan to do paint the upper hull. I am planning on using Rustoleum Topside white.
