Read MorePoor DOI Over Galvanized Steel
We would like to improve the Distinctness of Image (DOI) on our motorcycle fuel tanks and seek your advise for the same.

Read MoreReplaced Liner Just Isn't The Same As The Old
The liner on our Osrotron 10-cu-ft bowl wore out and we decided to reline rather than purchase a new machine.

Since spent fluorescent lamps contain mercury and can’t be thrown into our regular trash, what do we do about these switches?
Read MoreReactive Waste or Not Revisited
I would like more information on the organic sulfide precipitant described in the November 2006 column, “Reactive Waste or Not." Does it really work better than conventional neutralization/precipitation using acid/caustic and a flocculant?
Read MoreOverheated Nickel Sulfamate
We use a nickel sulfamate plating bath with a temperature range of 50–60°C to plate low stress micro-layers. Recently the temperature was allowed to reach 70°C. Did we ruin the plating bath because of this temperature upset? Can the plating bath be salvaged?
