The flash lightens the color a bit and there is reflection from the Future gloss-coat applied before painting the beard. Once it is dry it will get some dull coat. Then I can glue the deck to the hull and finish the odds and ends.

Hi Ed,
Looking good. The only thing I'm wondering about is if you should add more oil and sludge into the beard. I'd love to hear from some of the vets as to what these "beards" looked like since I need to do it for my two subjects.
Thanks!
Dave

Doing the algea line was one of the most difficult effects I've ever sprayed. Getting the color I wanted and edges, let alone getting it all to match the whole way around the boat, especially with the compound curves at the bow, made this nerveracking. If I had slipped up it probably would have resulted in repainting the entire hull (again).
I would like to add some sludge right at the waterline but I'm not sure my nerves could take it.

LOL Ed. I feel your pain. What technique did you use to paint the beard?

Dave,
I Future coated the waterline area and let it cure for a day. i found an artists tube-style acrylic paint called Permanent Tree Sap (yes, that was the name, honest). I mixed it to airbrush consistency with Tamiya airbrush thinner and practiced on some styrene sheet I had paint in the 3 boat colors and Futured.
I wanted a semi-hard edge at the waterline to look like the growth had been scrubbed away by the movement of the boat through the water. This edge could not be hard masked because it would have been produced by the passing water. It needed to be pretty straight and level but not mask edged. The time I was trying to model was the Battle of Surigao Straight and the Ron 33 arrived in the P.I. after sailing 1200 miles from New guinea just the day before the battle. That’s a lot of water to scrub the algae.
I wanted the top edge to be feathered, soft to look like growth that built up but was above the level where the water could do much scrubbing. Also, in the high pressure areas or areas where the boat experienced more scrubbing when at speed, I needed to narrow the algae band or make it thinner, lighter,
The last 2 complicating issues were the curves at the bow and that I had already glued the mufflers in place and would need to algae them and the boat behind them.
I found a photo of 109 showing a nice side shot on a cradle. I used it as a guide for the straight side sections. It had a taper, wider at the stern.
For the straight hull sides, I took a few manila folders and torn them in a straight line to produce a mask that was straight but not knife edge hard. I made one for the bottom side (waterline) and one for the top edge. Then I took .062 styrene strips and attached then to the hull with double-sided tape, keeping them below the waterline by 1/8” or so. I then stuck the bottom mask, torn side up to the styrene with more DS tape aligning the edge with the waterline. For the top edge of the growth I did the same thing but used .2 thick styrene strips and spaced them further away from the area to be painted. I positioned the upper mask, torn side down, at a point slightly below the top edge I want to end up with.
I set the airbrush for a light spray and, keeping some distance from the masks, started along the waterline and pretty perpendicular to the hull/mask. I ran up and down the waterline, putting as much paint on the mask as the hull until the color built up to the shade I wanted. As I went back and forth, I also moved out a bit and changed the angle of the airbrush to get some overspray under the upper mask to feather the top edge. That action along with the increased distance between the upper mask and the hull gave a much softer edge than the waterline side.
For the bow section, I couldn’t cut/tear masks that followed the curves correctly so I masked the waterline with 1/8” take set below the water by 1/16” or so and put down several layer to build up thickness. I ended by using ¼” tape overhanging the thick tape below on the waterline side. It’s edge followed the waterline. I couldn’t use this method for the upper edge so I made a little make, 2” long, with a ¼” spacer an the back. I held the small masking piece above the waterline and by moving the mask as I sprayed I was able to follow the upper edge I wanted by eye-ball. Very nerve racking, especially when trying to make the second side look like the first.
The stern was a PITA and I have gone back and touched it up to darken it a bit and level it out. Lost of masking and lots of free-hand.
If I had the nerve, I would coat it with future and soft-edge mask the bottom edge at the waterline. I would make the thick mix of “oily black” and mineral spirits to apply sparingly just above the waterline and then wipe off with only downward strokes to pull it toward the tape edge. The tape edge will build up a little residue that will least a dark, random-edged line right at the water’s edge.
Wow, sorry for the long post.
Ed

Ed,
Your 495's tropical "beard" looks pretty realistic.
I had lots of personal experience scraping the "beard" from the waterline of my Dad's two wooden-hulled work boats years ago in the Virgin Islands. Every few months, we'd anchor in a cove, go over the side with masks and fins, and scrape the barnacles off the waterline with putty knives and the sea grass with wire brushes. This was in the Caribbean, of course, but marine growth exists in all warm tropical waters, regardless of the ocean or copperoid anti-fouling bottom paint (which we used on our boats when we hauled them out of the water once a year to scrape and repaint the entire bottoms).

Thanks Drew. I'm working on the final details and don't plan to do anything else to the hull.
