<div dir="ltr">Congrats, and I can't wait to see her begin to come together! Just one thing about the Macropoxy. Although it's super durable, it does yellow even without sunlight. For a long time, each time I turned my attention to the sub for a new season I found the Macropoxy in good condition but needing a new coat just to keep it white. Now I've top-coated it, and it's stayed white. I can't recall what I used as a top coat, but it was some ordinary enamel rather than something with special marine industry prices. Even a single top-coat layer is a really good idea that will cut down on your work in the long term, if you want to keep it bright white. <div><br></div><div>Best,</div><div>Alec</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Mar 2, 2024 at 4:22 PM Jon Wallace via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:"times new roman","new york",times,serif;font-size:16px"><div dir="ltr"><div><div style="margin:0px;font-family:"Segoe UI Historic","Segoe UI",Helvetica,Arial,sans-serif"><div style="font-family:inherit"><font size="3" style="background-color:rgb(255,255,255)">I have reached a milestone with the K600, interior prep and paint finish is complete.

Most of the prep work involved using a wire brush on a grinder to loosen surface rust and feather the surrounding paint. The worst areas were below the main viewport, beneath the hatch area, and the bottom of the aft head. Using a wire brush cleaned the areas easily.</font></div></div><div style="margin:0.5em 0px 0px;font-family:"Segoe UI Historic","Segoe UI",Helvetica,Arial,sans-serif"><div style="font-family:inherit"><font size="3" style="background-color:rgb(255,255,255)">The aft section of the vessel was in much better condition than the fore section and in the aft I only spot coated the problem areas with POR-15. In the fore section there was much more area showing surface rust and pin prick rust spots. By the time I was done grinding them down it just seemed to make more sense to completely prime with POR-15 rather than just spot coat each area.</font></div></div><div style="margin:0.5em 0px 0px;font-family:"Segoe UI Historic","Segoe UI",Helvetica,Arial,sans-serif"><div style="font-family:inherit"><font size="3" style="background-color:rgb(255,255,255)">I used two coats of POR-15 as the primer and two coats of Macropoxy 646 as the finish coat. All very expensive paint but both providing a very durable and hard finish that I think will last a long time. I was impressed with the POR-15. After two coats it dried hard as a rock and felt extremely durable. I decided on an epoxy finish because I wanted something that would stick and bond to the POR-15, which the Macropoxy did without issue. The only thing I don't like about the Macropoxy is that it's a flat finish. I could have used Sher-Loxane instead but I didn't feel like spending another $240 for a glossy finish when I already had the Macropoxy available to me.</font></div></div><div style="margin:0.5em 0px 0px;font-family:"Segoe UI Historic","Segoe UI",Helvetica,Arial,sans-serif"><div style="font-family:inherit"><font size="3" style="background-color:rgb(255,255,255)">The conning tower was in very good shape and required minimal wire brushing. Here again I spot coated those exposed areas with POR-15 however for the finish coat I wanted a gloss finish. While the original paint was obviously durable given it's condition, it showed dirt and scuff marks from years of people climbing in and out of the vessel. I decided I had to have a gloss finish on the conning tower but again didn't want to spend hundreds of dollars for a gallon of Sher-Loxane when I needed less than a quart, so I simply overcoated the existing finish with gloss white Rust-Oleum. We'll see how it holds up.</font></div></div><div style="margin:0.5em 0px 0px;font-family:"Segoe UI Historic","Segoe UI",Helvetica,Arial,sans-serif"><div style="font-family:inherit"><font size="3" style="background-color:rgb(255,255,255)">The K600 now has $879 (US) in paint on it.
