Painting the hull
This is the part I have been dreading. I have never gotten good at applying paint, either with a brush, or spray, but here goes.
I first scribed lines on the bulwarks. It would have been easy to scribe the plank lines on the bulwarks before they were installed, but since I had the deck installed I had to do them in place. I made a scribe holder from a 1/2" thick piece of scrap aluminum about 1.5" wide and 1 5/8" high with three 6-32 holes tapped on 1/2" centers to give 1/2" spacing to the scribed plank lines. I ground a sharp point on some 6-32 machine bolts, mounted them through the plate, held them up under the inner rail, and scraped the lines into the bulwarks. Worked pretty well, but I could have held it more steady. I used acrylic enamel paint in spray cans, Rust-oleum Painters Touch for the flat black and metallic copper hull, and semi gloss Nason Ful-cryl II that was color matched to the yellow and red paint chips that came with the kit. The paint store didn't think the paint could be made flat successfully, so I took the semi. I had to buy the Nason in pints, much more than is needed, and had them put in spray cans for me. Rather expensive at about $25 per can total. I also got some good quality 3M masking tape. One was a very expensive flexible tape for using on the waterline and the yellow stripe which was a real help. I used cheap tape for applying the mask papers however. I prepared the surfaces to be painted by giving them a light sanding with an abrasive mat, much easier to use on the many curved surfaces than sand paper, and washed them with SCAT degreaser. After masking off the deck, I gave every thing several coats of primer. Then masked off the bulwarks and painted down to below the waterline with flat black. This looks pretty good, but has proven to chip easily and show light scrapes. I wish I had used semi gloss instead, it would have saved me time patching, and given a more durable finish. The masking must be applied carefully to make the yellow stripe along the side. The 1.5" wide stripe starts 1/8" below the rail from stem to stern. I made a flexible pattern to apply the lower tape mask. I took an 18" long 1/8x1/8" wood strip and glued four 1 5/8" long strips perpendicular to it. At the other end I glued short 1/8x1/8" strips that can be clamped up against the underside of the rail to locate the position for the lower edge of the stripe, and applied the flexible masking tape right against the pattern, moving it down the hull with me as I masked. The top of the stripe I marked by clamping a 1/8x1/8" wood strip up under the rail and marking with a pencil. What looked like a long touchy job to get smooth uniform curves was done in less than an hour. After painting the stripe, I marked the waterline. For some reason I thought it was parallel to the keel, but you have to prop up the bow to make the waterline parallel to the surface you are marking from. The hull packing foam was just the right thickness, and helped hold the hull up while I leveled and braced it with paint mixing sticks clamped to the rail. Then I used a height gage to mark the waterline with a pencil. After masking with the flexible tape, I sprayed with metallic copper paint. I was going to put a light green wash over the copper to tone it down. But it is not as bright as I thought it would be, and I like it as it is. The last thing was to paint the bulwarks red. I had only one problem here. The tape I applied on the outside of the gunports was too narrow and I had to apply two pieces to cover the ports. I didn't get a tight seal where the strips overlapped, and the red paint came out onto the yellow, which will take a lot of touching up. I would recommend 2" wide tape here! After I have touched up the runs, chips and blemishes, I will apply some clear flat Painters Touch spray I found to protect the copper and flat black. Then I can get on with the fore and aft upper decks, and the few other parts left to be applied to the hull to finish it. xhullx xbuildx
