I use Stuph but you can't buy it anymore so I keep it under lock and key.
Corrosion-X works well too. BD.

Kills Rust and Corrosion World's Greatest Lubricant, Penetrant & Anti-Seize Safe on Electronics CorrosionX is the most advanced and effective corrosion prevention compound, lubricant and penetrant in the world! Although it may look like a typical oil-based anti-corrosion spray, CorrosionX utilizes a revolutionary technology called Polar Bonding™ that does far more than merely slow down the corrosion process like those so-called 'corrosion inhibitors'. Corrosion-X actually kills existing rust and corrosion (keeping it from spreading) and provides long-term protection against rust and corrosion on any metal surface. Learn More | Brochure | Product Data Sheet | SDS | SDS (aerosol version) CorrosionX is the only product available to the public that meets the US Navy's tough new corrosion prevention and control performance requirement MIL-PRF-81309H. Corrosion Protection and Rust Preventive Coating Due to Polar Bonding, CorrosionX causes common metals and metal alloys such as iron, steel, stainless steel, aluminum, copper, brass, bronze, etc. to chemically behave more like noble metals such as gold and platinum. In other words, as long as CorrosionX is present on metal, it can't rust or corrode! CorrosionX also has a dielectric characteristic, so it's safe on electronics and completely shuts down electrolysis between dissimilar metals. Use CorrosionX wherever you want corrosion control without paint or wax coatings. A light spray of CorrosionX on power heads, gensets and engines a couple of times a year will keeping them looking like new – even in saltwater and coastal environments. To learn more about Polar Bonding, please visit our technology page. A Breakthrough Lubricant CorrosionX's unique formulation offers a multitude of advantages over conventional spray lubricants. Because it sticks to metal like a magnet, it cannot be easily displaced by pressure, friction or moisture. It lubricates under extreme loads and high temperatures. Not only does CorrosionX lubricate better, it lasts many times longer! This is especially true in outdoor, coastal and marine environments where direct exposure to rain and sea spray will quickly displace ordinary lubricants. Use CorrosionX on sheaves, hinges, locks, cable/wire rope, windlasses or any metal part needing lubrication. It is ideal for fishing reels and firearms. Unbeatable Penetrant CorrosionX also penetrates faster and further than anything you've ever used. Corroded or rusted nuts, bolts or fittings can usually be disassembled within a few minutes. Even items you believe to be hopelessly seized can usually be saved and returned to service. Watch this time lapse video closely! Due to it's unique Polar Bonding characteristic, CorrosionX is such an incredible penetrant that it will defy gravity and climb straight up this 3" bolt!! Safe On Electronics Water and electronics don't mix. Until now, there haven't been many options for protecting or restoring electronics from moisture intrusion. CorrosionX's unique Polar Bonding Fluid Thin Film Coating (FTFC) technology displaces moisture and seals it out with a self-healing high dielectric coating. Even though the CorrosionX has a dielectric property in excess of 39,000 volts, because it forms an ultra-thin film it does not interfere with electronics or heat dissipation. A must for all marine battery terminals, and a mission critical product for drones and all Remote Control hobbyists. Minimal Environmental Impact Product The volatile organic content (usually abbreviated as VOC or VOCs) of CorrosionX is now ZERO. Compare that to most products in the spray lubricant category, which can be 50% or more VOC (for example, according to their current Safety Data Sheet, WD-40 is 49.5% solvent). That means CorrosionX is many times more gentle on you, your equipment and the environment.

Thanks as always, BD !

Re: WET CONNECTIONS

Hi Kerry,
How is that monster Seaview coming? BD.

**kerry addington** · 06-21-2011, 09:42 AM

Re: WET CONNECTIONS

Well put, BD. She is indeed a monster.
First float test in primer two weekends ago proved my bilge pump-in-the-ballast-tank system far too slow and leak prone, so I am furiously ripping and refitting the tank for snorting. Frankenstein's belly now reduced to a mere 90 oz. capacity.
Hoping to be back in the swim for this weekend's SubRon6 FunRun at Carmel. I'll either be screaming
"It's... Alive !!!", or I'll jump in the pond and push it around like Peter Lorre with the shark.

Re: WET CONNECTIONS

Looking forward to seeing you and Seaview at the Regatta!

Re: WET CONNECTIONS

Where was it leaking, and what pump were you using?

If you want to snort, have a look at these pumps- http://www.sparkfun.com/products/10398

They move a lot of air, one may do, but you can always parallel up another if it's too slow for you.

Re: WET CONNECTIONS

As usual, great comment and help from you sir.
I will check those snort pumps.
The bilge pump I was using (rule 500gph) worked just fine. The air induction mast on the sail to have any believable scale was about 3/16" diameter-I think insufficient air was getting into the tank and some vaccuum backup/hiccups
were taking place. I really didn't have much opportunity to observe or tweak operation as my flood vent valve mounted sideways was not sealing correctly as one might suspect..and one canceled out the other.
So, I'm putting the solenoid vent on top and hopefully snorting toward this weekends FunRun. A vent/fill valve mounted on the underside of the tank is not an option for me. This DeBoer hull is a masterpiece and stronger than my car,but mid-1990's vintage, thick-walled and heavy. Foam everywhere and a 90-ounce tank sitting entirely below the waterline is just enough to get her up and proud.

Re: WET CONNECTIONS

That looks like an OLLLLLLLLDDDDDD Subtech vent valve.
I had one of them in my 1/48 Fleet boat back in 1994.
Just shows you quality items will last forever.
If you have to lift a big hull it is hard to beat a low pressure air system. That is how the bigboys do it!! BD.

Re: WET CONNECTIONS

BD misses nothing! That is indeed a mid-90's vintage Skip Asay with the Matt Thor mod package.
Nothing but the best for this big girl.

Re: WET CONNECTIONS

The vent valve should be on the bottom of the tank, not the side.

The snort system is really the water pump system turned upside down, up until a couple of weeks back I couldn't recommend it for a very large boat like this, because pumps of adequate displacement were difficult to source, that's no longer the case however with the availability of the Sparkfun pumps.

**bigdave** · 06-22-2011, 06:39 AM

Re: WET CONNECTIONS

How would you vent the air out the bottom?
My vent valves are all on top .
The side would only work to the height of the valve.
I feel time is but an issue with the low pressure air.
As the boat is already at the surface with the primary system I really don't care how long it takes the LPA to make the boat hit waterline. It will get there eventually. LOL!! BD.

Re: WET CONNECTIONS

I was referring to the water pump system, Dave. The tank is vented at the top via a mast, and has no valve, to fill the tank, you open a valve at the bottom of the tank, the tank free floods with gravity.

To empty the tank, you use a centrifugal pump, the valve is closed, and the pump started this empties out the tank, with the vent at the top allowing air in.

Re: WET CONNECTIONS

Got ya!! I figured it was a miscomunication somewhere. BD.

**Guest** · 06-22-2011, 08:19 AM

Re: WET CONNECTIONS

For the snort system, naturally a vent at the top, and free flood holes of large cross section at the bottom.

A solenoid valve might be a bit slow to vent, a servo controlled poppet valve sealed with a o-ring would do the trick, and you can size the valve to suit.
