Jeff,
It's hard to say about every paint department. There are 2000 stores in the company and 300,000+ employees. But I can say that around here there seems to be at least one very knowledgeable person at every store I deal with. Because of the economy there are a lot of displaced highly experienced people working at HD, here in Pittsburgh there just aren't a lot of jobs.
Sam,
Where you live there are generally some good and knowledgeable people at that store. The problem we run into though is that some people rather than admitting that they don't have an answer for you will try and pretend something like black oil paint doesn't exist. In Pennsylvania its due to EPA laws, selling what we all think of as oil paint became illegal in 2005. And at that time HD stopped selling regular oil house paint. We were allowed to sell off our existing stock but it went very fast to contractors. Now there are ways to get around that. First there are DTM's or direct to metal paints, which still can be sold, something like Rustoleum. And PPG reformulated their oils to comply with the new law, and you can buy them at stores in Pittsburgh that sell PPG procucts. The old PPG stores here were bought out by Masterworks a few years back so that's where I would look. But unless you have one of the new contractors licenses that became law this year in PA the only quantity you can buy is a quart. There are several outlets around where a contractor can get larger quantities of oils such as Wheelers and the old Sternbergers on route 51, which is now the main store for Masterworks. Now recently the guys I know at Sherwin Williams have informed me that they have started selling oils again that meet the EPA standards. You may also find oils available at some local hardware stores but if it is in a gallon I'd be real careful that it isn't old stock. I've heard from several of the paint company reps that I deal with who call on hardware stores also that they have been running into old stock now and then. Frequently in my store the people I work with and myself, will send a customer somewhere else to get what they need. Happens every day, for example I get asked for "boat paint" all of the time. We don't sell marine grade paints but I know of several places that do so I send them there.
Al,
No I've never been asked for "skyhooks".
