1946 Chris Craft Brightside U22 Bottom Paint!

1946 chris craft brightside u22 bottom painting

Since the last update video, we have applied five coats of Interlux 2000E two-part primer, followed by the requisite blue bottom paint, ePaint’s Ecominder Antifouling Bottom Paint in this case.

One more coat of ePaint Ecominder, a water-based one-part antifouling paint and this 1946 brightside U22’s True 5200 bottom is complete.

What is ePaint Ecominder antifouling paint? Here is what Jamestown Distributors answers:

New ePaint Ecominder is the greenest and most effective copper-free antifouling paint available.

Ecominder uses a copper-free, water-based, zero VOC paint formula that is safe and easy to apply. It keeps boat hulls clean using hydrogen peroxide generated from sunlight and the environmentally preferred booster biocide Zinc Omadine.

Designed for use on all rigid type surfaces including fiberglass, aluminum, and wood, it is compatible over other bottom paint systems, and can even be applied in cool ambient temperatures. It is very popular in the pontoon market due to its compatibility with aluminum substrates. Ecominder is available in a variety of colors including White, Gray, Green, Blue, and Black.

ePaints contain no tin or copper. Instead of following the age-old method of leaching toxicants that persist in the environment, ePaints employ a novel mechanism to control the attachment of fouling organisms. When immersed in oxygenated water, all ePaints photochemically generate minute levels of peroxides. The minute levels of peroxides make the surface inhospitable to the settling larvae of fouling organisms. Hydrogen peroxide is a potent, but short-lived chemical that has traditionally been used as an antiseptic. Peroxides have been demonstrated to be effective antifouling agents. The peroxides do not persist in the environment because they quickly decompose back into oxygen and water by natural ions dissolved in the water.

Because ePaints contains no copper, they are available in white as well as a variety of bright colors. The lack of copper also ensures that ePaints are compatible with aluminum and other metals in the marine environment. This is not the case with copper-based paints that promote galvanic corrosion with metal boats. ePaints are safer for you, your boat, and our environment.

With a home port of Ahmic Harbour in Magnatawan, Ontario, this U22 lives and plays on one myriad of lakes in Canada’s Muskoka lake region where the water remains clear and pristine. By using Ecominder on her bottom, we ensure that, at least she, will introduce no additional copper to Ahmic Lake. That the paint is water-based, has zero VOCs is a plus for us while applying it in the shop. One more coat, then the paper comes off. One the remaining topside Dutchman repairs are executed and the entire surface, including the transom’s, is sanded fair, she will be flipped upright for the first time in over seven months.

We are just beginning to see a glimmer of the finish line peeking over the horizon!

1946 Chris Craft Brightside U22: How to Paint Bottom

1946 chris craft brightside u22 how to paint bottom

Paint! I could claim that it seems like only yesterday when we launched the preservation of the mahogany (Brightside) 1946 Chris-Craft U22, but I can’t. In truth it’s been a long, long, and sometimes frustrating slog.

As we replaced most of the bottom and transom framing, both chine frames, and most of both chines; and worked to remove the corkscrew and hog from the hull, days, weeks and months flew by. Were we making progress? Yes, but it was so difficult to see and feel any.

Not now! Her True 5200 bottom is complete to the point of applying her Interlux 2000E InterProtect Primer and her Econominder, copper-free, Chris-Craft blue antifouling paint.

The last of four coats of Clear Penetrating Epoxy Sealer has been applied. Tomorrow, after it has cured, we will hand sand the bottom lightly, thereby preparing a smooth and uniform surface for the first coat of 2000E, which I will apply later today.

We apply the first coat from the keel to the top of the boot stripe, let it cure 24 hours and then mask the boot stripe so we do not build layers beneath the Interlux Brightside Enamel we will use for the boot stripe. Brightside adheres better to Interlux PreKote than it does to 2000E in our experience. PreKote in turn adheres tenaciously to the 2000E.

Four additional thin coats of 2000E will be applied, followed by four coats of Econominder antifouling paint.

Then comes a truly BIG day. We will flip her upright and begin stripping varnish off and bleeding old stain out of the decks and covering boards.

Next comes sanding fair, bleaching, staining and, yes, varnish! Now that will be the day to smile.

1953 Shepherd Model 110 S Sportsman True 5200 Bottom Update

The July 9 ACBS show in Gravenhurst, Ontario is racing at us. We are committed to bring Orca, my 1953 22’ Shepherd Model 110-S Sportsman. As this video portends, many a late night are in our future!

But her 331 cubic inch, dual-quad-four, V-drive Hemi is on track. Robert Henkel, Robert Henkel Inc. (chris-craft-parts.com) has engaged a comprehensive tear-down and re-build that will include porting, polishing and balancing among a long list of particulars. The purple monster is on schedule and will be back and install-ready by the first week of May.

And the hull? Well Mickey Dupuis, Custom Restoration, Holyoke, MA, has finished working his magic on the hardware.

Shauna, Kocian Instruments, Forest Lake, MN (kocianinstruments.com), reports that the instrument cluster’s preservation will also be back by early May.

Her original wheel needed a complete preservation. Once again the pros at PearlCraft, Rowville, Victoria, AU (pearlcraft.au) transformed a totally shabby wheel into jewelry.

The Marmoleum is in hand, and the upholstery is in process.

ALL that is left is finishing the hull… all..

By the end of the week we will have applied all five coats of Interlux Interprotect 2000E two-part epoxy barrier coat will have been applied. Installing the True 5200 bottom will be complete. Three coats of hard racing bronze bottom paint will follow.

Then off comes the paper and out come the longboard sanders for the final topside and transom planking, followed by staining and sealing.

After flipping her over, I “get” to strip the decks and covering boards…

Seems so straightforward… guess we will just let her romp on Lake Champlain in June… yes?

1930 Dodge Runabout Barriercoating the True 3M5200 Bottom

1930 Dodge Runabout True 3M 5200 Bottom

Our “True 5200 Bottom” project on the 1930 Dodge Runabout, the Minnow, has reached the barrier coat stage. In this clip we illustrate the foam-roller application of the second of will be five coats of Interlux 2000E Barrier Coat Primer. Five coats? Really? Yes.

In Danenberg’s words, “One of the biggest problems I’ve seen with shortcut 5200 bottoms is either a total lack of, or inadequate amounts of, Interlux 2000E Barrier Coat Primer. This two-part (thus epoxy) paint is a water barrier coat meant to keep the water from soaking into the bottom planks. It does this with minute platelets in its makeup that vastly slow the movement of water. Unlike hard epoxy laminating glues, it is flexible enough to move with the bottom.

“It is a very important part of the true 5200 bottom. It helps stabilize the bottom construction, keeping adequate moisture in the wood during extremely dry winter storage, and keeping excess moisture out of the wood during summer use. Its use is meant to stop excessive expansion/contraction that cracks open paint coatings, elongates screw holes, and buckles or cracks planks and frames.

“This product’s instructions call for a 10-mill thickness, usually 4-6 rolled-on coats (no sanding between coats), or two gallons for the average 20-footer. If your restorer tells you that 2 coats are enough, he is wrong.” (Classic Boating, September-October 2014, p. 25.)

Yes, Interlux 2000E is pricey, $92/gallon plus hazmat and shipping from Jamestown Distributors, but price and cost so often inversely correlated, and this is an example of that principal. Spend an extra $200 or so in paint now to save thousands repairing failed fasteners and planking way too soon in the future.
