I have always used SEM for my interior paints but for my Regal I just wanted a can of matching paint to do my trio gauge panel but it was not available through SEM so I bought a can from Gbodyparts and sprayed my panel and it was a good match to my original dash, I wouldn't hesitate to use it again.
The below picture is before mounting it to the dash.

Any and and all colors are available but not all are made in an aerosol can. You can send something to SEM and they'll scan it, get the formula, custom mix the color and make a quart or gallon for you. Or they'll email you the formula and you can have a paint supplier mix it. This last time I had them do it because of the fiasco I had with the local place I usually deal with. Of course you need a spray gun to put it on but its very easy to use. Its ready to use right out of the can. Just stir it up, pour it into the cup and spray. No thinning. And it dries really quick. I did well over 20 pieces for my friends 79 Camaro and he took them home the same day.
