Do not use lacquer on meteorites, period!? In this day and age, dealers should know better. Any time I see it, I think "lacquer is for lazy people who do not want to take the time to polish properly."? There is no substitute for a good polish which reduces the surface area and repels moisture.? Lacquer traps moisture in the meteorite and hastens disintegration.? Just ask anybody who has owned a Lacquer covered Brenham!? I had one completely fall apart and the only thing holding together was the lacquer finish. It held it together just long enough to make it to my trashcan.

Happy Collecting,

Adam

Hello List
Need help :-(

I have beautifull big slice of Seymchan 1mm thin. I wanted to put it to new membrane frame toogether with my 2mm Brahin and 1mm Shirokovsky so I start clean them from oil using acetone.
Unfotunatelly I didn't know that Seymchan was covered with very thin varnish layer. Acetona damaged varnish so I need to remove it. Now slice dont look nice as before becouse polishing is not same on whole surface, varnish make it look super polished.

Im not fan of using such protections on any meteorite so I have no experience in this topic. I need sugestions how to put thin and clear varnish layer. I should use normal clear varnish in spray or something else ?

Thanks
