Hello
Any way of getting off those colorful hardened
epoxy or whatever it is that they put on the reverses
of some silver eagles. Have a 2002 (not colorized) but was
in an encasement ring (screw on type) as part of a money clip.
Obv. is normal but the rev. has a raised clear and colored type coating on it that mimics the actual rev. of the eagle.
Seems to be clear coated also and no seam to pry it off etc.
Heat, soak, hand grenade ? :)
Thanks

Most, epoxy or resins will dissolve in "TIME" in acetone, it might be fairly quick hours or could be days! it might also soften enough to peel most of it off, or just dissolve over a period of days. You could use heat but the problem them becomes the black fire scale that could develop on the silver due to the heat and if heated to hot, some of the sire scale may never come off with out the application of some mechanical means.  |

O.K. Thanks all. Will try the acetone
after I try some old fashioned zip strip
that I just remembered that I had.
It worked great on those colorized ones and as long
as the coin was rinsed very well after the paint came off
it did no damage or discoloration of the silver or coins
surface.

Thanks Dave. I was always careful with it
but did not know about the water thing.
I used to rinse objects off in the sink (stainless steel sink)
after the paint was removed. Do not remember any neg. effects
though. Would it just be damage to the metal or causes a gas
or ?

I'm thinking that if you've used it successfully, then you're doing it right.  It's the metal itself that's in danger of corrosion, not the user. |

The deal with any of the hot solvent paint strippers is they will do damage to plastic and metal pipes/sinks if they are washed down with large amounts of water! That's why the instructions general state that you should scrape off as much as possible and dispose of the sludge in newspaper before washing with water changing often. A lot of people don't want to use the water freely do to either the cost of the water, the sewer /treatment charges or both in the towns and cities. Also all though it works well on paint it may not work well on set-up epoxy. If the piece was a commercially produced item. it is more than likely is an industrial grade formula epoxy. So it may not work as well. |

I would think acetone would make quick work of it.

O.K., all set now. No damage has been done over the years. I only used it for small items etc. and used a Q-tip to apply it. Will now get my acetone in gear.  |

Polyester Resin - very simple for my Dad's coins. Take a 5 lb sledge, put the resin block on a concrete floor and give it a tap, then a bigger tap. Just did 5 of them. A couple I had to pry out. Resin sticks slightly less to coin and comes out clean. Usually one face is clean, other still embedded. Simply put face down on a softer-than-silver material, like plexi, and give it a whack. Bingo, ka'ching !
For urethane or epoxy resin, may be different. They are more flexible, less brittle. Polyester is the one that smells when you cut it.
