marble lovin

I have been collecting for years but hadn't seriously gotten into it until the last couple years. I have trouble telling them apart. I have tried to make a couple resin marbles but am having trouble getting them to shine I don't know what kind of clear coat to use or how to hold the marble up to put it on. I would live to know how to restore marbles like you do can you please give me any information you can. Thank you so much!! Marbles Lovin [email protected]

I would be interested but how much is something like that?
