can a formica countertop be resealed ?

nulisecundus asked: we recently bought a home that has a formica countertop in the kitchen. It seems as though someone used a harsh chemical to clean it. Now simple coffee stains are very hard to remove. Is there anything that can reseal the surface?

How do I know for sure if there is a meth lab in my neighborhood, and if so what can I do to stop it?

blue eyes asked: I definitely smelled a harsh chemical (like a cleaning agent) outside a home tonight. I live in a nice neighborhood and don’t want this around our kids. What do you think?
