Has anyone tried this stuff on a plexiglass windshield? It sure works great on glass.

Well, a similar product has been used on airplane windscreens for years.

GAWhaler, do you have insight on this?

I thought it would be great for the Mills Canvas windshield, but was told not to use it on anything but glass. I think the bottle may say that also - not sure.

JB,
Be careful what you put on PLEXI. A good coat of some spray on waxes will accomplish the same desired effect. I use Mc Guires spray wax and cleaner on my other boat windshield. Works great !

lhg,

There is a great product that cleans and takes some of the haze out of those clear flexible windshields. Used it on a weathered Katama winshield. I will get the product name and purchase point and repost.

Thanks for that, Jim, and thanks for offering a while back to send me a pattern for the Katama windscreen. I ended up getting one from Mills (discussed in another post) and will probably need some sort of plexi cleaner down the line.

Instead of wasting your money try this! 1st clean the windshield with Windex or what ever,wipe it dry, when completly dry rub bar soap all over it. Then wet the windshield with plain water and gently wipe it off. If you want to see how this works at home, do the same with your bathroom mirror and see what happens when you take a hot shower....clean dry glass! I use this method at work. I wear plexiglass safety glasses. They never fog up and when I go outside during rain,they stay clear!

The lable on my bottle states:
"DO NOT USE on scratch resistent or specially coated plastics unless pre-approved by the manufacturer of the plastic"

Their web site www.rainx.com states that the marine version is safe for plexiglass.

Don't think I would use it without approvel from my windshield manufacturer.

Do not ever use any product that contains alchohol and this includes Windex on your acrylic windshield.Alchohol and acrylic or Plexiglass do not mix.Alchohol will cause the plastic to crystalize and crack.
If you do not believe this pour some alchohol on a piece of acrylic and let it set for awhile.
Polycarbonate is OK with alchohol.

I keep a bottle each of Meguiars plexiglass cleaner and polish around (they work well, by the way) for maintaining the vision panels in my Mills canvas and the console windshield, not exactly the same issue that you posed, though JB. But as long as I'm slightly OT anyway, I'll offer up something I learned about soft plexiglass last summer that at least lhg knew already, but might be of value to others.

I unrolled my canvas and put it up just after dark one night on a Labor Day mini-rendezvous at Charlevoix, MI last year. It had been stored in one of my cooler seats for a number of weeks since its last use. The next morning, when there was enough light to see, the vision panels were completely, but evenly fogged, (they were pretty much opaque) so I dried them off and got out the Meguiars and went to work on them. Couldn't touch the fog - it was like it was *inside* the plastic. I was convinced that fumes from a can of acetone I'd stored in the same cooler with the canvas for a litle while had escaped the container and permanently ruined my plastic.

I'd been working on the panels for about an hour when lhg rolled out of the sack and strolled over, witnessed my dejection, and told me he thought it was just moisture causing the fog; he said he had seen it before on his canvas when it had put away wet. I thought back and recalled that I had put my canvas away wet, and had forgotten to unstow it and dry it out as I had intended. Larry said that if it was moisture, it would slowly clear up, but might take a couple of days to clear up completely. Well, it apparently was moisture, because as the day wore on, the vision panels became clearer and by the next day they were OK (and well polished).

I had no idea that plexiglass was subject to temporary fogging from simple moist conditions in a small enclosure, but it apparently is. The good news is that it will fix itself.

The product that I spoke of earlier has a # assigned to it. 303 or 305. It is available at West Marine or Boat US. Comes as a aeresol or a liquid. USE THE AERESOL. I have used it on a Katama Windshield/windscreen and the huge clear flexible wind screen on a PENN YAN.

Hope this is of some help

I agree with Nedspoint.........The best I have ever used on plastic is Pledge. Used it for years on plastic rear windows on my convertibles. Never use anything with alchohol on plastic.

in the summers I work for a tour company that uses large aluminum boats with wrap around plexi windows (the boats are the same as the cats for new york water way) anyway rainx on the windows all the time no problems. the only thing to worry about is if you have a tight bend in the plexi. on a hot day the rainx will cool it really fast and possably cause cracks. but I have only seen that on windows that are curved.

Honda spray cleaner that was designed for motorcycle plastic windshields works better than any other product I have used. It won't scratch, polishes and has antistatic properties. It comes in a red and black can. Just follow the Harley guys with their heads hung low at the Honda parts counter. Rating A+++

I use rainx on my motorcycle windscreens and they are fine. I also use it on my helmet, get caught in the rain and just turn your head sideways, clears the shield. Bugs come right off too.

I ride motocross and for the goggles (plexy lense) I found that non-abrasive car wax works better and lasts longer than RainX. I've been using a bottle of Nufinish that was laying around in the garage. It also works great on the car windows.

kingfish,

A friend with a large Hatteras with a fully enclosed (in plastic) flying bridge, uses an interesting method that has his screens looking new after almost ten years. He rolls each panel with a layer of wax paper. The "slippery side" of the paper goes against the plastic and rolls up with the panel. Apparently, in addition to the moisture problem, it also prevents the plastic from sratching itself.

Are we talkin isenglass or plexiglass?

With a plastic window I have been told many things but the most important being...NEVER dry it, especially with a towel. Let them drip dry.

With plexiglass like our console windshields anything goes. I have buffed them with buffers and used wd-40 to mmake them look new again, whatever it takes should work. UV rays are what destroy them and make them Sparkle, etc. They are basically "bulletproof" glass just thinner and tinted.

I use rain-x on my windshield, inside and out (wet boat). No problems after 2 years of use.
