[meteorite-list] Clear Coat Iron Slices?

[Pete Pete]

Hi, Walter,

About a year ago I bought a Dronino that the seller had coated with a 
urethane-type substance, and I can tell you that there are a few definite 
drawbacks from this procedure:

-Underneath the coating, lawrencite disease has started up and in many 
places broken through the seal. I'm sure that it's progress has been slowed 
because of the coating, but short of using a harsh chemical to remove the 
shell, likely damaging the meteorite in the process, treatment is 
impossible.

-The coating has a subtle yellowish hue, and under the microscope it becomes 
vey annoying.

-Personally, I find the direct contact with a meteorite aesthetically 
pleasing.

Cheers,
Pete

Hello Everyone,

I was wondering if anyone had an opinion on coating iron slices with some 
type of clear coat to help prevent rust?  Pros?  Cons?

Would driving off as much water as possible then applying the clear coat 
work?  Are harmful gasses trapped by the process?

Any discussion or opinions would be appreciated.
