help finding old post: caring for coins in Dansco

ad4400

I recall a post a while back that I can't for the life of me find after trying a number of searches. It was in the context of putting high end coins in a 7070 and covered the gamit from the common sense (making sure coins are all the way in the hole) to the novel (using canned air to clear debris out of a hole before putting a coin in) plus a host of other ideas, the specifics that now escape me. If anyone recalls and can find that post, can they link it here?

This is the best Dansco 7070 thread on the forums. Not sure if it's the one yer talkin' about though.
