Plastimo Contest compass liquid
 

My elderly Plastimo compass has deleloped a bubble inside the globe.
Does anyone know what type of liquid Plastimo uses to damp the card?

Many thanks in advance

Matt

I don't know about Plastimo but I believe a lot of compasses (compii?)
use distilled kerosene. The trick is getting it in. I spoke with a shop
once that did it and they adviced getting a new compass.

I believe that most compasses are filled with mineral OIL, not spirits.
Of course, I'd check the your specific manufacturer to be sure.

I'm not sure about Plastimo, but Silva uses mineral spirits.

Mine was definitely mineral SPIRITS, as the smell is unmistakable.
Mineral oil would be much too thick for a small compass, anyway and
might not work at all in cold weather.

Don't know about Plastmo, but for aircraft compasses, check
http://www.aircraftspruce.com/catalo...repairkit1.php

$1.71 for 1/2 pint which has to be the least expensive thing they've ever
sold. (before shipping)

Roger (forty or fifty years ago it was ethyl alcohol -- the good stuff)

1/2 mineral spirits (deodorized kerosene), 1/2 mineral oil.

I like your input of ethyl alcohol filler, in case of emergency it goes well
with Coke.
