Could I spray this device (in a cabinet) with varnish to protect from ambient moisture on my boat?

easiest and safest way to protect from ambient moisture (high humidity or splash protection) is to use Liquid Tape (http://smile.amazon.com/Gardner-Bender-LTB-400-4-Ounce-Electrical/dp/B000FPAN2K/ref=sr_1_1?s=industrial&ie;=UTF8&qid;=1436879033&sr;=1-1&keywords;=liquid+tape) , which is basically liquid electrical tape that hardens when exposed to air. Using the Liquid Tape, apply to all exposed solder points, or simply brush across each side of PCB, be careful not to coat the surface area on the integrated circuit (IC, small thumbnail size black 5-pin component), as that IC must dissipate heat.

I would advise against varnish. You do not want to put an insulating material over electronics that can get hot. I also would not worry about ambient moisture, even on a boat. Just mount it vertically. If you are worried about it getting splashed, then you can Google, "Conformal Coating" and read up on it.

Polyurethane or acrylic(brush on or spray) would work well but the switches would need some sort of protection. Another product that works well is corrosion X, it's a spray and leaves a very thin coating, great for almost everything that needs waterprofing. All of these will allow resoldering if needed, they vaporise on contact with a soldering iron. Plasti dip or liquid electric tape is the last thing I would use. Its too thick, has poor thermal characteristics (keeps heat in), and its a pain to remove if needed.

Yes you can seal it to protect it but not varnish! Find a good electronics store (not Radio Shack) Someone that knows electronics there are a couple of different products that will work but they are not cheap. good luck

Yep, I would enclose it in a project box, seal it and mount it. You could even cut out a window to view the volt meter.. Depending on current, you could trap in the heat using film across the board..

Not sure how well poly or clear coat would really protect it. You would be better off putting it in a small waterproof enclosure.

This should work well as a lot of mariners use it to waterproof their maps when boating. I would put at least 3 coats on, with a drying time of 1 hour between each coat.

No, I am sorry this is a light duty item. I use mine for luggage, jewelry boxes, inside my safe, closed areas that would not be exposed to constant moisture. You could try damp rid it handles larger areas; however I think that you may need something more heavy duty like a dehumidifier.

You're going to have to apply them carefully using a heat gun. Unfortunately, the way the boat is textured, they won't stick well without heat.

I only did indoor cabinets with their water based top coat...in my experience though and living in cold weather, I would think you would need an oil based top coat for an outside door! :)

My impression is that it needs a contained space in order to be effective, so I guess my answer is I don't know, it depends. Can you contain the material which sprays out of the top in the effected area reasonable well for a few hours? For a small fairly open boat, my gut reaction would be no. For a larger boat with a cabin area which is the effected area I would say probably. I would take as much stuff out as possible and air it out. Then with all the drawers, cabinets open, but the space reasonably sealed, give it a try. The product is alcohol based so remove possible sources of ignition during the spraying and for a half an hour or so afterwards.

If it is the outside, I would think it would be fine, but if it is the inside, not so sure, since it is in contact with water on a regular basis. I would try a couple coats of primer and a couple coats of rustoleum. It is worth a try.

I don't know the answer to this question but I would assume that it would not be a good idea to use other than dry ingredients. I say this because the device would have to be made to prevent moisture from getting into the mechanisms and the warranty would probably not be honored.

I don't think so. Any varnish is made with oil which is made to penetrate into wood, obviously not possible with a vinyl surface. There are a number of protective finishes specifically made for vinyl (particularly vinyl siding) and this is what I would go for.

If I were to do a project like yours, I think I would use the marine varnish. Or epoxy. Epoxy is messy and very difficult. I don't know of anything that will really protect from the AZ sun other than powder coating, which is a metal thing. and baked about 280 degrees. The answer is yes..maybe. I'd do it.

I never tried to do that, but I don't think it would be too good for that since it is mostly relatively coarse sand and the like which would not easily squeeze into a fine crack. Even Portland cement, which is finer may not penetrate well enough, though you might try that, hoping to preserve to some degree the appearance of your sink. But if looks aren,t too important perhaps clear liquid epoxy would seal better, or even a liquid super glue. Also, I suppose that you could later scour the "glaze" of glue off of the surface with scouring powder and elbow grease. The method would be to use as little glue as possible,yet to try to "rub" it into the crack.

Yes this is some of the best marine varnish available. You'll still need to make sure you follow the directions closely and re-apply a couple times per year if it takes a beating from the sun and moisture.

I have sprayed garage cabinets to truck bumpers and plastic fender flares with this stuff. It should adhere fine if you prep the surface well.

I am not sure...it is electric so don't know how the moisture would affect it. I agree you should contact the manufacturer to be sure.

yes...you will want to get a UV spray so it doesn't fade...I made decals for my boat and it worked out fantastic!

I don't see why not. It's completely waterproof once it sets. But honestly if you are worried about leaks, I would get a plastic sink base tray from Revashelf. It channels the water in a way so that it won't end up resting in the cabinets. I sell cabinets and love the tray!
