RainX on Lower Helm glass?

Anyone use RainX on their lower helm glass windows for better visibility? *We have a windshield wiper but it's smaller than I'd like and I've not added one to the middle or port glass. *We are about to do a 3-4 day trip soon and thought I might put some rainx on the glass. *I've used it on cars and love it and can't imagine why it'd be a bad idea on the trawler but thought I'd see if others have used it? *On my truck it makes a huge difference in visibility in a driving rain!

RE: RainX on Lower Helm glass?

I've tried Rain-X periodically for years and have never found it to be worth much. On the boat it does nothing EXCEPT if we are getting heavy spray in rough water and IF the Rain-X coating is brand new. Then the water sheets off the windshield very nicely.

But in light spray, fog mist, and the light rain we get a lot here Rain-X accomplishes nothing because the individual droplets are not heavy enough to slide down the windshield by themselves. Rain-X does make it easier for the wipers to clear them, however.

The big problem with Rain-X that we've found is that in a salt water environment it doesn't last very long. Maybe for one run into the islands out and back if we're getting salt spray on the windows. I don't know if it's the presence of the salt or what, but after a day of spray and clearing it with the wipers, the Rain-X is pretty ineffective after that.

We occasionally use it on our vehicles where the higher speed of the vehicle helps clear the water. But even then we've not been impressed with it. Even following the application instructions to the letter and polishing it with a clean cloth, it still increases glare at night and makes streaks.

Up here the only way we've found to effectively clear the light mist from fog, light rain, and light spry is wipers. If you boat in heavy rain I suppose Rain-X would help for awhile. But even when Rain-X is working as advertised, you have all this water running down the windshield which doesn't obstruct your "big picture" vision but can make it very difficult to see debris in the water, which we have a ton of up here from crab pot floats to boat-sinking deadheads. The only sure way to see those things is with the windshield panes absolutely clear and the only way we've found to do that effectively is with good wipers.

GBs typically have very good wipers--- ours does and it's an ancient '73 boat--- but we found that the wiper blade arc in the most critical pane, the center one, didn't come down quite far enough for my wife to see the water directly in front of us when she was steering or helping watch for debris in the water. Fortunately one of the Grand Banks forum members who lives in Seattle came up with a brilliant way of installing a parallel arm wiper on a GB without having to drill any holes. He made us the part he had designed so now we have a longer parallel arm wiper on the center windshield pane which makes a huge difference. The stock wipers are fine on the two outboard panes.

But a lot of people swear by Rain-X including the owner of the BMW shop we use. He says he never turns his wipers on at all, although every time I've ridden with him or he's followed me in his car in the rain, he's turned his wipers on . But I would definitely give it a try rather than taking anyone's word for it. Your boat's windshield configuration, the kind of water on the glass you have to deal with, and other variables may make it a good solution for you.* We always drive our boat from the lower helm, never from up above, and in our waters good visibility, especially right up close to the boat is critical. We have found the only consistent and effective solution is good wipers.

RE: RainX on Lower Helm glass?

I use it on the front windows of the pilot house and only use the wipers every few months to see if they still work.

And furthermore, RainX doesn't make as much noise as the wipers when it is working.

The solution to that is to have two Ford Lehman 120s hammering away directly under your feet.* Our wipers are dead silent when they're working

RainX on Lower Helm glass?

I hate the D*****M stuff. I put it on my cars and boat. Huge mistake. Once on if you don't keep a fresh coat on it will screw up the vision so badly that it looks like you have a hazy film over your eyes. or a heavy oily mess that WILL NOT COME OFF.
Great when absolutely fresh, absolute crap if you don't refresh it often.

Once on you cannot get rid of it. It's silicone or silicone based and nothing I tried would remove it;
acteone, laquer thinner, xylene, alcochols,

DON"T DO IT.

I have a cleaner called "tumbler" that makes short work of silicone based coatings. Bought it at an auto body shop supply store.

Our Defever came with really lame wipers. The center one we look through the most only covered about 30% of the window, and was way too high to see clearly in front of the boat.* My solution was to open the wiper motor assembly, and adjust the arc.* On most wiper assemblies the drive gear has a series of holes that adjust the sweep angle.* Simply move the arm to a different hole to adjust, (they are marked in degrees)* Then I bought a much longer wiper blade (at an auto parts store), and cut off the top 1/3 of it.* We now can see through most of the window, .* The remaining windows had the sweep adjusted and new blades installed.* In addition, we RainX all our pilot house windows and like it, but Fred's comment about the stuff getting old explains the differing results we get from time to time. We use it on the cars too...........Arctic Traveller

Thanks Keith,

At the time I asked around but no one knew.
The cars are long gone and the boat windows also. I will admit the boat windows were changed for other reasons. But never again.

RainX on Lower Helm glass?

I have had no problems with it and find it does seem to help vision wise. Like Marin said it will not work in the same fashion as on a car where the forward speed whips the rain off. Maybe it's that*the very act of applying it makes the glass cleaner.

Woodsong

Give it a try but make sure that your windows are very clean before you apply it for the first time
i have used it on large commercial vessels that didn't have wipers so it was all we had and it seemed to work ok
My understanding was that you didn't use your wipers whilst you were using Rain-X

Woodsong,
I have been using RainX on my wheelhouse windows for the last 15 years and love the stuff.
never had a set of wipers that can do as good a job. Use the old formulat full strength the watered down stuff is not as good IMHO.

We avoided windshield wipers on Delfin because my experience with them is that they are salt spray smearers, reducing visibility not increasing it.* Instead, we use RainX coupled with fresh water nozzles that we use to spray clean H2O on the glass when it gets coated.* Very satisfactory solution.

Why do you hate it on your car? *I've used it on my trucks here and there over the years and always loved it!

I hate it on the car because once you use a wiper on it the streaks start. Why use a wiper you say? Well here in Flooooorida, you must use your wipers when it is raining. Coast Guard has no such rule.

Ever tried dishwashing liquid to stop the windshield from fogging up on the inside*

Works great.

RE: RainX on Lower Helm glass?

We've done this on occasion using a dilution of Lemon Joy. It does work after a fashion. However it eventually results in a cloudy look out the glass and has to be cleaned off.
