compass lens haze

Gang,

My cover keeps falling off my compass lens and it's slowly been turning opaque from UV exposure. Is there any product like the ones "as seen on TV" that has worked for anyone to rub the hazing out?

Just looked at new compasses and was thinking you know maybe $99.99 would get me a replacement. I was wrong x 4.

Re: compass lens haze

I had some scratches and haze on my very old compass. I took some wet sand paper, 800 grit, got the scratches out, then polished the whole thing with toothpaste. Looks great!

No problemo!

Re: compass lens haze

If you don't get around to polishing it right away, just rub a little mineral oil on it. Available at a pharmacy. Won't hurt anything, and will bring back a lot of transparency with no effort.

Re: compass lens haze

You can buy a headlight polishing kit complete with polishing pad to put in your drill at any auto parts chain, that will bring it up to a new finish again.

Or you can DIY. The main brand name of plastic polish is "Novus", use #1, 2, 3 in sequence and you can make all the plexi on your boat look new. Sandpaper...probably the long hard way to work on rounded surfaces, compared to a polishing wheel/pad and the right polishes.

Traditional Crest toothpaste (not the gel or fancy stuff) uses diatomaceous earth aka fuller's earth as the "polish" abrasive, and that's also exactly the right stuff to put a fine polish back on plexi or polycarbonate--if it isn't too bad to start with.

If you really want to take it all the way to "brand new" finish up with 3M Finesse, also an auto paint polish but something like a 3000 "grit" equivalent.

If you can find one big cheap pair of athletic white tube socks...that's two compass cover retainers for two bucks.

Re: compass lens haze

Thank you for the suggestions gang. I think I'll try one of these and see if I can get a before and after shot up. I figured the auto lens restore would work but didn't want to fall for the infomericial. I think I'll try with some toothpaste first and see what happens.

Re: compass lens haze

depending on the make of the compass and if you can get replacement parts ... I've replaced the globe, diaphragm and gaskets on my Ritchie compass .. and it's like new ... way cheaper than buying new!! and not that hard to do ...

This is Ritchie's Catalogue. At the end is a list of service centers. In 2008, I mailed my compass to Howard Wilson in Tuckerton NJ, He re-built it to look like new for $65.00.

New compensating magnets, new fluid, new lense and a paint job. Great Service! Nice Guy!

Re: compass lens haze

I agree with skywalker, 800 to a 1000 grit wet sand followed by a toothpaste pollish it worked for my 40 yr old and greatly hazzed compas. cheap and easy with great results.
