Four Winns Horizon with Volvo 4.3 SX Cobra<br /><br />As the last step of winterizing the manual says to spray the entire engine with anti rust spray.<br /><br />Any recomendations on what spray to use (WD40) ?<br /><br />What about belts and hoses, do these get sprayed as well?

Back when I had jet ski's and ran them in salt water I would flush the motors with a hose and then spray the whole engine compartment down with WD40. I never developed any rust and it kept the motors looking new.

The idea is good but the product choice is surely not the best.There are many better choices of an engine coating at your local marine store.Some specifically for that application.Boeshield is one but it is a little pricey.Charlie

I have used WD in a total spray down after winterizing since the 1970's, on my boats , motorcycles, lawnmowers, whatever. Wash/hose it off in the spring if it shows (motorcycles-etc) or under cowls ignore. Watch the belts though. Zero problems 40 years

I'm with Robby - WD40 means "Water Displaced, 40th attempt" so displacing water is what designed for. I spray down down both engines and then cover them with a mylar engine blanket and never get any rust as a result. I don't even try getting off the WD40 in the spring. I just start up and go w/o a problem. I'm sure as the engines heat up a lot off it flashes off.

Re: Coating Engine with WD40 ?

My experience has been that wd40 is just a water displacment. It has no rust inhibitors. In storage there is no mo water after duecing with the stuff so it appears to prevent rust.<br /> <br />Sand blast a piece of metal, soak with wd4o and leave outside for a few nights.<br /><br />You decide. <br /><br />Cheers.

Re: Coating Engine with WD40 ?

I had heard that "WD" was water displacement too, but the "40" stood for days so it may or may not last long enough. On my snowmobiles I used to use WD40 but for the past several years I've used a penetrating oil and then foaming engine cleaner to clean it off in the fall.<br /><br />There are probably better products but this method is cheap and easy.

Ahhhhh Yes, WD-40, the Swiss Army Knife of spray cans. Jack of all trades, Master of none.<br /><br />You should try something designed to be a corrosion guard, and it's not a water dispersant.<br />Also, covering things in plastic is a good way to promote condensation. And from the sounds of things a mylar blanket is nothing more than an advertisers word for a sheet of plastic. The reality is, it stops air circulation and promotes condensation.<br /><br />PS: I live where there is a lot of moisture, 160 to 180 inches of rain a year. Seattle gets 36" a year so you have something to compare it to.

Re: Coating Engine with WD40 ?

I don't care what WD stands for, or its claims. Its works good enough for me,...always has. And thats from snowmobiles in the 70's in the Midwest, to the boats and motors here in Puget Sound. Keeps the rust at bay externally good enough, while the saltwater is slowly eating up the innards. And I have tried Boeshield, CRC, and the others, in simple test. Basically all snake oil in salt environment. If I wanted to preserve this junk of mine, instead of using it, I would cover it in cosmoline. Life's a mystery, a fun trip, not a problem to be solved. And in case we forget, EVERYTHING we make, mother nature will reduce to waste in time. Everything......so use it up first.

Everytime I returned from a salt or fresh water cruise I would rinse off the out drive and drench it down with WD-40 and other than paint chips 5 years later it looked as good as it didwhen I bought it. I have tried Boeshield and didn't find it any better just more expensive. Buy the WD-40 in a gallon can and put it in a spray bottle.

Thats what I do. And as to WD being junk snake oil, how come every household owns a can? The rest of the so called corrosion snake oil is just a variation of the same, with silicone and veg oil, probably a little "3 in 1", touch of gear lube, a little Brut for smell, and a great New York ad firm

Me too. Ultimate snake oil riding the WD success story. Got a $9 can sitting on the shelf collecting dust. See if I can get a dollar for it at the next garage sale. Last year in the spring, I hung an aluminum plate off the saltwater dock, with WD, boeshield, and marine grease. Before the barnacles tool over anyway (mother nature will always destroy manmade items), WD held up the best for a couple weeks, the crap slide off the grease, and I have a can of Boeshild that they must have forgot to put the magic ingredient in..........

I think I will use the WD-40. How liberally do you apply it?

Thanks for all the great responses, back to my original post<br /><br />What about belts and hoses, do these get sprayed as well?

Re: Coating Engine with WD40 ?

From an e-mail about WD-400:<br />WD-40 <br />I thought that you might like to know more about this well-known WD-40 product. When you read the "shower door" part, try it. It's the first thing that has cleaned that spotty shower door. If yours is plastic, it works just as well as glass. It's a miracle! Then try it on your stovetop... Viola! It's now shinier than it's ever been. You'll be amazed. <br /><br />The product began from a search for a rust preventative solvent and degreaser to protect missile parts. WD-40 was created in 1953 by three technicians at the San Diego Rocket Chemical Company. Its name comes from the project that was to find a "Water Displacement" compound.<br />They were successful with the Fortieth formulation, thus WD-40. <br />The Corvair Company bought it in bulk to protect their Atlas missile parts. The workers were so pleased with the product they began smuggling (also known as "shrinkage" or "stealing") it out to use at home. <br /><br />The executives decided there might be a consumer market for it and put it in aerosol cans. The rest is history. It is a carefully guarded recipe known only to four people. One of them is the "brew master." There are about 2.5 million gallons of the stuff manufactured each year. It gets its distinctive smell from a fragrance that is added to the brew. Ken East (one of the original founders) says there is nothing in WD-40 that would hurt you. <br /><br />Here are a few of the 1000s of uses: <br />~Protects silver from tarnishing<br />~Cleans and lubricates guitar strings<br />~Gets oil spots off concrete driveways<br />~Gives floors that 'just-waxed' sheen without making it slippery<br />~Keeps flies off cows<br />~Restores and cleans chalkboards<br />~Removes lipstick stains<br />~Loosens stubborn zippers<br />~Untangles jewelry chains<br />~Removes stains from stainless steel sinks<br />~Removes dirt and grime from the barbecue grill<br />~Keeps ceramic/terra cotta garden pots from oxidizing<br />~Removes tomato stains from clothing<br />~Keeps glass shower doors free of water spots<br />~Camouflages scratches in ceramic and marble floors<br />~Keeps scissors working smoothly<br />~Lubricates noisy door hinges on vehicles and doors in homes<br />~Gives a children's play gym slide a shine for a super fast slide<br />~Lubricates gear shift and mower - deck lever for ease of handling on riding mowers<br />~Rids rocking chairs and swings of squeaky noises<br />~Lubricates tracks in sticking home windows and makes them easier to open<br />~Spraying an umbrella stem makes it easier to open and close<br />~Restores and cleans padded leather dashboards and vinyl bumpers<br />~Restores and cleans roof racks on vehicles<br />~Lubricates and stops squeaks in electric fans<br />~Lubricates wheel sprockets on tricycles, wagons and bicycles for easy handling<br />~Lubricates fan belts on washers and dryers and keeps them running smoothly<br />~Keeps rust from forming on saws and saw blades, and other tools<br />~Removes splattered grease on stove<br />~Keeps bathroom mirror from fogging<br />~Lubricates prosthetic limbs<br />~Keeps pigeons off the balcony (they hate the smell)<br />~Removes all traces of duct tape<br />~I have even heard of folks spraying it on their arms, hands, and knees to relieve arthritis pain. ~Florida's favorite use was "cleans and removes love bugs from grills and bumpers<br />~The favorite use in the state of New York<br />~ WD-40 protects the Statue of Liberty from the elements.<br />~WD-40 attracts fish. Spray a LITTLE on live bait or lures and you will be catching the big one in no time. It's a lot cheaper than the chemical attractants that are made for just that purpose. Keep in mind though, using some chemical laced baits or lures for fishing are not allowed in some states.<br />~Keeps away chiggers on the kids <br />~Use it for fire ant bites. It takes the sting away immediately, and stops the itch. <br />~WD-40 is great for removing crayon from walls. Spray on the mark and wipe with a clean rag. <br />~Also, if you've discovered that your teenage daughter has washed and dried a tube of lipstick with a load of laundry, saturate the lipstick spots with WD-40 and re-wash. Presto! Lipstick is gone! <br /><br />~If you sprayed WD-40 on the distributor cap, it would displace the moisture and allow the car to start. (If I knew what a distributor cap was, it might help) <br /><br />~WD-40, long known for its ability to remove leftover tape smudges (sticky label tape), is also a lovely perfume and air freshener! Sprayed liberally on every hinge in the house, it leaves that distinctive clean fresh scent for up to two days! <br /><br />~Seriously though, it removes black scuff marks from the kitchen floor! Use WD-40 for those nasty tar and scuff marks on flooring. It doesn't seem to harm the finish and you won't have to scrub nearly as hard to get them off. Just remember to open some windows if you have a lot of marks. <br /><br />~Bug guts will eat away the finish on your car if not removed quickly! Use WD-40!

What about belt dressing? Does it help prolong the life of belts, or just make em grip better?

Belt Dressing would work fine. I still question the WDing of rubber belts......("~Lubricates fan belts on washers and dryers and keeps them running smoothly")........although the rusty pulleys I get in the spring on my big boat sure could use something.
