Joe, yes, this stuff does look great by itself, but eventually over time it WILL absorb moisture like any other primer, i personally use DAR9000 black (over the top of the dp for chasis), but it has a shine to it, GM makes a chassis black which they sell by the quart or gallon, but I personally have not used it, so i can't say much for its looks or its durability. it may be possible to add a flattening agent to the DAR9000 black, but i am not sure. where are you from?? maybe i could lead you to a paint shop if you are in my area. perhaps the body man you spoke to meant to use this over the bare steel first and then apply something over the top?? if you are not from my area i could also supply you with a phone number of my local paint store who know their stuff very well, it would be worth the small long distance fee. By the way if you use the DAR9000 black, use the PPG hardener as well with it and the durability will then be great!!!don't let them talk you into the generic har! dener with this paint. I would surely think any body shop would know that the DP product needs to be top coated!! in fact i was at a seminar that had a PPG rep at it who did not recommend this by itself- he said he had seen some street rods with it on, driving around in the weather and he cringed. the DP line has changed recently due to the EPA - It used to be DP40 (grey-green) DP90 (black) etc, now it is DP40LF which means lead free, and it also does not have the acid etch it used to have, i don't remember which one you said you used, but if it was the LF- the surface should have been etched with either a etch primer or a metal prep- wash (metal prep 79) unless it was just sandblasted within 72 hrs then the DP or DPLF can go right on with out the prep.
